Significant Accounting Policies | 1:SIGNIFICANT ACCOUNTING POLICIES | |||
Principles of Consolidation: CMS Energy and Consumers prepare their consolidated financial statements in conformity with GAAP. CMS Energy’s consolidated financial statements comprise CMS Energy, Consumers, CMS Enterprises, and all other entities in which CMS Energy has a controlling financial interest or is the primary beneficiary. Consumers’ consolidated financial statements comprise Consumers and all other entities in which it has a controlling financial interest or is the primary beneficiary. CMS Energy uses the equity method of accounting for investments in companies and partnerships that are not consolidated, where they have significant influence over operations and financial policies but are not the primary beneficiary. CMS Energy and Consumers eliminate intercompany transactions and balances. | ||||
Use of Estimates: CMS Energy and Consumers are required to make estimates using assumptions that may affect reported amounts and disclosures. Actual results could differ from those estimates. | ||||
Revenue Recognition Policy: CMS Energy and Consumers recognize revenue from deliveries of electricity and natural gas, and from the transportation, processing, and storage of natural gas, when services are provided. CMS Energy and Consumers record unbilled revenue for the estimated amount of energy delivered to customers but not yet billed. CMS Energy and Consumers record sales tax net and exclude it from revenue. CMS Energy recognizes revenue on sales of marketed electricity, natural gas, and other energy products at delivery. | ||||
Alternative-Revenue Program: In 2009, the MPSC approved an energy optimization incentive mechanism that provides a financial incentive if the energy savings of Consumers’ customers exceed annual targets established by the MPSC. The maximum incentive that Consumers may earn under this mechanism is 15 percent of the amount it spends on energy optimization programs, which is limited to two percent of Consumers’ retail revenue. Consumers accounts for this program as an alternative-revenue program that meets the criteria for recognizing revenue related to the incentive as soon as energy savings exceed the annual targets established by the MPSC. | ||||
Self-Implemented Rates: Unless prohibited by the MPSC upon a showing of good cause, Consumers is allowed to self-implement new energy rates six months after a new rate case filing if the MPSC has not issued an order in the case. The MPSC then has another six months to issue a final order. If the MPSC does not issue a final order within that period, the filed rates are considered approved. If the MPSC issues a final order within that period, the rates that Consumers self-implemented may be subject to refund, with interest. Consumers recognizes revenue associated with self-implemented rates. If Consumers considers it probable that it will be required to refund a portion of its self-implemented rates, then Consumers records a provision for revenue subject to refund. | ||||
EnerBank: EnerBank provides four types of unsecured consumer installment loans: same-as-cash, zero interest, reduced interest, and traditional. Under EnerBank’s same-as-cash programs, authorized contractors pay EnerBank a fee to provide a borrower with the option to pay off the loan interest-free during the same-as-cash period. EnerBank recognizes the fee on a straight-line basis over the same-as-cash period, which typically ranges from three to 24 months. If a borrower does not exercise its option to pay off its loan interest-free during the same-as-cash period, EnerBank charges the borrower accrued interest at the loan’s contractual rate on the outstanding balance from the origination date. Under the zero interest and reduced interest programs, authorized contractors pay EnerBank a fee to provide a borrower with no interest or reduced rates of interest for the entire term of the loan. EnerBank recognizes the fee using the interest method over the term of the loan, which ranges from one to 12 years. | ||||
EnerBank recognizes interest income using the interest method and amortizes loan origination fees, net of certain direct origination costs, over the loan term. EnerBank ceases recognizing interest income when a loan loss is confirmed or when a loan becomes 120 days past due, at which time the loan principal is charged against the allowance for loan losses. At that time, EnerBank recognizes any interest accrued but not received for such loan losses as a reversal of interest income. | ||||
The loan fees and interest income earned by EnerBank are reported as operating revenue on CMS Energy’s consolidated statements of income. | ||||
Accounts Receivable: Accounts receivable comprise trade receivables and unbilled receivables. CMS Energy and Consumers record their accounts receivable at cost, which approximates fair value. CMS Energy and Consumers establish an allowance for uncollectible accounts based on historical losses, management’s assessment of existing economic conditions, customer trends, and other factors. CMS Energy and Consumers assess late payment fees on trade receivables based on contractual past-due terms established with customers. CMS Energy and Consumers charge off accounts deemed uncollectible to operating expense. | ||||
Cash and Cash Equivalents: Cash and cash equivalents include short-term, highly liquid investments with original maturities of three months or less. | ||||
Contingencies: CMS Energy and Consumers record estimated liabilities for contingencies on their consolidated financial statements when it is probable that a liability has been incurred and when the amount of loss can be reasonably estimated. CMS Energy and Consumers expense legal fees as incurred; fees incurred but not yet billed are accrued based on estimates of work performed. This policy also applies to any fees incurred on behalf of employees and officers under indemnification agreements; such fees are billed directly to CMS Energy or Consumers. | ||||
Debt Issuance Costs, Discounts, Premiums, and Refinancing Costs: Upon the issuance of long-term debt, CMS Energy and Consumers defer issuance costs, discounts, and premiums and amortize those amounts over the terms of the associated debt. Upon the refinancing of long-term debt, Consumers, as a regulated entity, defers any remaining unamortized issuance costs, discounts, and premiums associated with the refinanced debt and amortizes those amounts over the term of the newly issued debt. For the non‑regulated portions of CMS Energy’s business, any remaining unamortized issuance costs, discounts, and premiums associated with extinguished debt are charged to earnings. | ||||
Derivative Instruments: In order to support ongoing operations, CMS Energy and Consumers enter into contracts for the future purchase and sale of various commodities, such as electricity, natural gas, and coal. These forward contracts are generally long-term in nature and result in physical delivery of the commodity at a contracted price. Most of these contracts are not subject to derivative accounting because: | ||||
· | they do not have a notional amount (that is, a number of units specified in a derivative instrument, such as MWh of electricity or bcf of natural gas); | |||
· | they qualify for the normal purchases and sales exception; or | |||
· | there is not an active market for the commodity. | |||
Consumers’ coal purchase contracts are not derivatives because there is not an active market for the coal it purchases. If an active market for coal develops in the future, some of these contracts may qualify as derivatives. Since Consumers is subject to regulatory accounting, the resulting fair value gains and losses would be deferred as regulatory assets or liabilities and would not affect net income. | ||||
Consumers also uses FTRs to manage price risk related to electricity transmission congestion. An FTR is a financial instrument that entitles its holder to receive compensation or requires its holder to remit payment for congestion-related transmission charges. Consumers accounts for FTRs as derivatives. All changes in fair value associated with FTRs are deferred as regulatory assets and liabilities until the instruments are settled. | ||||
CMS Energy and Consumers record derivative contracts that do not qualify for the normal purchases and sales exception at fair value on their consolidated balance sheets. Each reporting period, the resulting asset or liability is adjusted to reflect any change in the fair value of the contract. Since none of CMS Energy’s or Consumers’ derivatives has been designated as an accounting hedge, all changes in fair value are either reported in earnings or deferred as regulatory assets or liabilities. CMS Energy and Consumers did not have significant amounts recorded as derivative assets or liabilities at December 31, 2014 or 2013. Additionally, the gains and losses recognized in earnings were not significant for the years ended December 31, 2014, 2013, or 2012. | ||||
Determination of MRV of Plan Assets for DB Pension Plan and OPEB Plan: CMS Energy and Consumers determine the MRV for DB Pension Plan assets as the fair value of plan assets on the measurement date, adjusted by the gains or losses that will not be admitted into the MRV until future years. CMS Energy and Consumers reflect each year’s gain or loss in the MRV in equal amounts over a five-year period beginning on the date the original amount was determined. CMS Energy and Consumers determine the MRV for OPEB Plan assets as the fair value of assets on the measurement date. CMS Energy and Consumers use the MRV in the calculation of net DB Pension Plan and OPEB Plan costs. For further details, see Note 12, Retirement Benefits. | ||||
Earnings Per Share: CMS Energy calculates basic and diluted EPS using the weighted-average number of shares of common stock and dilutive potential common stock outstanding during the period. Potential common stock, for purposes of determining diluted EPS, includes the effects of non‑vested stock awards and contingently convertible securities. CMS Energy computes the effect on potential common stock using the treasury stock method or the if‑converted method, as applicable. Diluted EPS excludes the impact of antidilutive securities, which are those securities resulting in an increase in EPS or a decrease in loss per share. For EPS computations, see Note 15, Earnings Per Share – CMS Energy. | ||||
Financial Instruments: CMS Energy and Consumers record debt and equity securities classified as available for sale at fair value as determined from quoted market prices or other observable, market-based inputs. Unrealized gains and losses resulting from changes in fair value of these securities are determined on a specific-identification basis. CMS Energy and Consumers report unrealized gains and losses on these securities, net of tax, in equity as part of AOCI, except that unrealized losses determined to be other than temporary are reported in earnings. For additional details regarding financial instruments, see Note 7, Financial Instruments. | ||||
Impairment of Long-Lived Assets and Equity Method Investments: CMS Energy and Consumers perform tests of impairment if certain triggering events occur or if there has been a decline in value that may be other than temporary. | ||||
CMS Energy and Consumers evaluate long-lived assets held in use for impairment by calculating the undiscounted future cash flows expected to result from the use of the asset and its eventual disposition. If the undiscounted future cash flows are less than the carrying amount, CMS Energy and Consumers recognize an impairment loss equal to the amount by which the carrying amount exceeds the fair value. CMS Energy and Consumers estimate the fair value of the asset using quoted market prices, market prices of similar assets, or discounted future cash flow analyses. | ||||
CMS Energy also assesses equity method investments for impairment whenever there has been a decline in value that is other than temporary. This assessment requires CMS Energy to determine the fair value of the equity method investment. CMS Energy determines fair value using valuation methodologies, including discounted cash flows, and assesses the ability of the investee to sustain an earnings capacity that justifies the carrying amount of the investment. CMS Energy records an impairment if the fair value is less than the carrying amount and the decline in value is considered to be other than temporary. | ||||
Inventory: CMS Energy and Consumers use the weighted-average cost method for valuing working gas, recoverable base gas in underground storage facilities, and materials and supplies inventory. CMS Energy and Consumers also use this method for valuing coal inventory, and they classify these amounts as generating plant fuel stock on their consolidated balance sheets. | ||||
CMS Energy and Consumers account for RECs and emission allowances as inventory and use the weighted-average cost method to remove amounts from inventory. RECs and emission allowances are used to satisfy compliance obligations related to the generation of power. | ||||
CMS Energy and Consumers use the lower-of-cost-or-market method to evaluate inventory for impairment. | ||||
MISO Transactions: MISO requires the submission of hourly day-ahead and real-time bids and offers for energy at locations across the MISO region. CMS Energy and Consumers account for MISO transactions on a net hourly basis in each of the real-time and day-ahead markets, netted across all MISO energy market locations. CMS Energy and Consumers record net hourly purchases in purchased and interchange power and net hourly sales in operating revenue on their consolidated statements of income. They record net billing adjustments upon receipt of settlement statements, record accruals for future net purchases and sales adjustments based on historical experience, and reconcile accruals to actual expenses and sales upon receipt of settlement statements. | ||||
Property Taxes: Property taxes are based on the taxable value of Consumers’ real and personal property assessed by local taxing authorities. Consumers records property tax expense over the fiscal year of the taxing authority for which the taxes are levied based on Consumers’ budgeted customer sales. The deferred property tax balance represents the amount of Consumers’ accrued property tax that will be recognized over future governmental fiscal periods. | ||||
Reclassifications: CMS Energy and Consumers have reclassified certain prior-period amounts on their consolidated financial statements to conform to the presentation for the current period. These reclassifications did not affect consolidated net income or cash flows for the periods presented. | ||||
Renewable Energy Grant: In 2013, Consumers received a renewable energy cash grant for Lake Winds® Energy Park under Section 1603 of the American Recovery and Reinvestment Tax Act of 2009. Upon receipt of the grant, Consumers recorded a regulatory liability, which Consumers is amortizing over the life of Lake Winds® Energy Park. Consumers presents the amortization as a reduction to maintenance and other operating expense. Consumers recorded the deferred income taxes related to the grant as a reduction of the book basis of Lake Winds® Energy Park. | ||||
Restricted Cash and Cash Equivalents: CMS Energy and Consumers have restricted cash and cash equivalents dedicated for repayment of Securitization bonds and for payment under performance guarantees. CMS Energy and Consumers classify these amounts as a current asset if they relate to payments that could or will occur within one year. | ||||

Regulatory Matters | 3:REGULATORY MATTERS | ||||||||
Regulatory matters are critical to Consumers. The Michigan Attorney General, ABATE, the MPSC Staff, and certain other parties typically participate in MPSC proceedings concerning Consumers, such as Consumers’ rate cases and PSCR and GCR processes. These parties often challenge various aspects of those proceedings, including the prudence of Consumers’ policies and practices, and seek cost disallowances and other relief. The parties also have appealed significant MPSC orders. Depending upon the specific issues, the outcomes of rate cases and proceedings, including judicial proceedings challenging MPSC orders or other actions, could have a material adverse effect on CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations. Consumers cannot predict the outcome of these proceedings. | |||||||||
There are multiple appeals pending that involve various issues concerning cost allocation among customers, the allocation of refunds among customer groups, the adequacy of the record evidence supporting the recovery of Smart Energy investments, and other matters. Consumers is unable to predict the outcome of these appeals. | |||||||||
Regulatory Assets and Liabilities | |||||||||
Consumers is subject to the actions of the MPSC and FERC and therefore prepares its consolidated financial statements in accordance with the provisions of regulatory accounting.

Regulatory Assets | |||||||||
Securitized Costs – Electric Utility Restructuring Legislation: In 2000, the MPSC authorized Consumers to securitize certain qualified costs incurred as a result of electric utility restructuring legislation. Consumers is amortizing this regulatory asset over the life of the related Securitization bonds. | |||||||||
Energy Optimization Plan Incentive: In May 2014, Consumers filed its annual report and reconciliation for its energy optimization plan, requesting approval of its energy optimization plan costs for 2013. In November 2014, the MPSC approved a settlement agreement authorizing Consumers to collect $18 million from customers during 2015 as an incentive payment for exceeding statutory targets under both its gas and electric energy optimization plans during 2013. | |||||||||
During 2014, Consumers achieved 135 percent of its electric savings target and 129 percent of its gas savings target. For achieving these savings levels, Consumers will request the MPSC’s approval to collect $17 million, the maximum incentive, in the energy optimization reconciliation to be filed in 2015. | |||||||||
Major Maintenance: In its 2012 order in Consumers’ electric rate case, the MPSC allowed Consumers to defer major maintenance costs associated with its electric generating units in excess of the costs approved in the rate order and to recover those excess costs from customers, subject to MPSC approval. In November 2014, the MPSC approved a settlement agreement authorizing Consumers to recover $10 million of such excess costs over a six-month period beginning December 2014. | |||||||||
Cancelled Coal-Fueled Plant Costs: In its 2012 order in Consumers’ electric rate case, the MPSC authorized recovery over a three-year period of $14 million of development costs associated with Consumers’ cancelled 830‑MW coal-fueled plant. In 2012, a party in Consumers’ electric rate case filed an appeal with the Michigan Court of Appeals to dispute the MPSC’s conclusion that authorized Consumers to recover these costs. In April 2014, the Michigan Court of Appeals affirmed the MPSC’s conclusion, which can no longer be appealed and is closed. | |||||||||
Gas Revenue Decoupling Mechanism: The MPSC’s 2009 order in Consumers’ gas rate case authorized Consumers to implement a gas revenue decoupling mechanism. This mechanism, which the MPSC extended through April 2012 in its 2010 order in Consumers’ gas rate case, allowed Consumers to adjust future gas rates to the degree that actual average weather-adjusted sales per customer differed from the rate order. In 2013, the MPSC approved Consumers’ final reconciliation of the gas revenue decoupling mechanism and Consumers collected $17 million during 2014. | |||||||||
Postretirement Benefits: As part of the ratemaking process, the MPSC allows Consumers to recover the costs of postretirement benefits. Accordingly, Consumers defers the net impact of actuarial losses and gains as well as prior service costs and credits associated with postretirement benefits as a regulatory asset or liability. The asset or liability will decrease as the deferred items are amortized and recognized as components of net periodic benefit cost. For details about the amortization periods, see Note 12, Retirement Benefits. | |||||||||
Securitized Costs – Electric Generating Units to be Retired: In December 2013, the MPSC issued a Securitization financing order authorizing Consumers to issue Securitization bonds in order to finance the recovery of the remaining book value of seven smaller coal-fueled electric generating units that Consumers plans to retire in April 2016 and three smaller natural gas-fueled electric generating units that it plans to retire in June 2015. Upon receipt of the MPSC’s order, Consumers removed the book value of the ten units from plant, property, and equipment and recorded this amount as a regulatory asset. Consumers is amortizing the regulatory asset over the life of the related Securitization bonds, which it issued through its subsidiary Consumers 2014 Securitization Funding in July 2014. For additional details regarding the Securitization bonds, see Note 5, Financings and Capitalization. | |||||||||
MGP Sites: Consumers is incurring environmental remediation and other response activity costs at 23 former MGP facilities. The MPSC allows Consumers to recover from its natural gas customers over a ten-year period the costs incurred to remediate the MGP sites. | |||||||||
ARO: The recovery of the underlying asset investments and related removal costs of recorded AROs is approved by the MPSC in depreciation rate cases. Consumers records a regulatory asset and a regulatory liability for timing differences between the recognition of AROs for financial reporting purposes and the recovery of these costs from customers. The recovery period approximates the useful life of the assets to be removed. | |||||||||
Unamortized Debt Costs: Under regulatory accounting, any unamortized debt costs related to debt redeemed with the proceeds of new debt are capitalized and amortized over the life of the new debt. | |||||||||
Gas Storage Inventory Adjustments: Consumers incurs inventory expenses related to the loss of gas from its natural gas storage fields. The MPSC allows Consumers to recover these costs from its natural gas customers over a five-year period. | |||||||||
Regulatory Liabilities | |||||||||
Income Taxes, Net: These costs represent the difference between deferred income taxes recognized for financial reporting purposes and amounts previously reflected in Consumers’ rates. This net balance will decrease over the remaining life of the related temporary differences and flow through current income tax benefit. | |||||||||
In September 2013, the MPSC issued an order authorizing Consumers to accelerate the flow-through to electric and gas customers of certain income tax benefits associated primarily with the cost of removal of plant placed in service before 1993. The order authorized Consumers to implement a regulatory treatment beginning January 2014 that will return $209 million of income tax benefits over five years to electric customers and $260 million of income tax benefits over 12 years to gas customers. During 2014, Consumers returned $64 million of income tax benefits to customers. | |||||||||
Renewable Energy Grant: In 2013, Consumers received a $69 million renewable energy grant for Lake Winds® Energy Park, which began operations in 2012. This grant reduces Consumers’ cost of complying with the renewable portfolio standards prescribed by the 2008 Energy Law and, accordingly, reduces the overall renewable energy surcharge to be collected from customers. The regulatory liability recorded for the grant will be amortized over the life of Lake Winds® Energy Park. | |||||||||
Cost of Removal: These amounts have been collected from customers to fund future asset removal activities. This regulatory liability is reduced as costs of removal are incurred. The refund period of this regulatory liability approximates the useful life of the assets to be removed. | |||||||||
Renewable Energy Plan: Consumers has collected surcharges to fund its renewable energy plan. Amounts not yet spent under the plan are recorded as a regulatory liability, which is amortized as incremental costs are incurred to operate and depreciate Consumers’ wind parks and to purchase RECs under renewable energy purchase agreements. Incremental costs represent costs incurred in excess of amounts recovered through the PSCR process. | |||||||||
Energy Optimization Plan: At December 31, 2014 and 2013, surcharges collected from customers to fund Consumers’ energy optimization plan exceeded Consumers’ spending. The associated regulatory liability is amortized as costs are incurred under Consumers’ energy optimization plan. | |||||||||
Power Supply Cost Recovery and Gas Cost Recovery | |||||||||
The PSCR and GCR ratemaking processes are designed to allow Consumers to recover all of its power supply and purchased natural gas costs if incurred under reasonable and prudent policies and practices. The MPSC reviews these costs, policies, and practices in annual plan and reconciliation proceedings. Consumers adjusts its PSCR and GCR billing charges monthly in order to minimize the underrecovery or overrecovery amount in the annual reconciliations. | |||||||||
Underrecoveries represent probable future revenues that will be recovered from customers and are included in accrued gas revenue on Consumers’ consolidated balance sheets. Overrecoveries represent previously collected revenues that will be refunded to customers and are included in accrued rate refunds on Consumers’ consolidated balance sheets. Presented in the following table are the assets and liabilities for PSCR and GCR underrecoveries and overrecoveries reflected on Consumers’ consolidated balance sheets: | |||||||||

PSCR Plans and Reconciliations: In May 2014, the MPSC issued an order in Consumers’ 2012 PSCR reconciliation, approving full recovery of $1.9 billion of power costs and authorizing Consumers to roll into its 2013 PSCR plan the underrecovery of $18 million. | |||||||||
Consumers submitted its 2013 PSCR plan to the MPSC in September 2012, and in accordance with its proposed plan, self-implemented the 2013 PSCR factor beginning in January 2013. In March 2014, Consumers filed its 2013 PSCR reconciliation, requesting full recovery of $1.9 billion of power costs and authorization to roll into its 2014 PSCR plan the overrecovery of $10 million. | |||||||||
Consumers submitted its 2014 PSCR plan to the MPSC in September 2013, and in accordance with its proposed plan, self-implemented the 2014 PSCR factor beginning in January 2014. Consumers’ power supply costs for 2014 were significantly higher than those projected in its 2014 PSCR plan due to severe winter weather during the three months ended March 31, 2014, as extreme cold weather and heavy snowfall inhibited the delivery and use of coal at Consumers’ coal-fueled generating units. Additionally, increases in natural gas prices raised the cost of electricity purchased from the MISO energy market as well as the cost of power generated at Consumers’ natural gas-fueled generating units. Consumers filed an amendment to its 2014 PSCR plan in March 2014, requesting approval to increase the 2014 PSCR factor. Consumers self-implemented the revised factor in July 2014. Consumers had a $6 million PSCR overrecovery at December 31, 2014. | |||||||||
GCR Plans and Reconciliations: In September 2014, the MPSC issued an order in Consumers’ 2012-2013 GCR reconciliation, approving full recovery of $0.9 billion in gas costs and authorizing Consumers to roll into its 2013-2014 GCR plan the underrecovery of $22 million. | |||||||||
The MPSC approved Consumers’ 2013-2014 GCR plan in July 2014, authorizing the 2013-2014 GCR factor that Consumers self-implemented beginning in April 2013. Due to the impact on natural gas prices of extended periods of colder-than-normal winter weather in Michigan and throughout the United States during the three months ended March 31, 2014, Consumers’ natural gas fuel costs for this period were significantly higher than those projected in its 2013-2014 GCR plan. As a result, Consumers calculated an $84 million underrecovery for the 2013-2014 GCR plan year. In the reconciliation it filed in June 2014, Consumers requested full recovery of $0.9 billion of gas costs and authorization to roll into its 2014-2015 GCR plan the underrecovery of $84 million. | |||||||||
Consumers submitted its 2014-2015 GCR plan in December 2013, and in accordance with its proposed plan, self-implemented the 2014-2015 GCR factor beginning in April 2014. Due to the significant underrecovery Consumers experienced during the 2013-2014 GCR plan year, Consumers filed an amendment to its 2014-2015 GCR plan in February 2014, requesting approval to increase the 2014-2015 GCR factor to be charged to customers. In May 2014, the MPSC issued an order authorizing Consumers to charge the increased factor to customers until the MPSC issues a final order in Consumers’ 2014-2015 GCR plan. Consumers had a $27 million GCR underrecovery recorded at December 31, 2014. | |||||||||

Cost of Removal: These amounts have been collected from customers to fund future asset removal activities. This regulatory liability is reduced as costs of removal are incurred. The refund period of this regulatory liability approximates the useful life of the assets to be removed. | |||||||||
Renewable Energy Plan: Consumers has collected surcharges to fund its renewable energy plan. Amounts not yet spent under the plan are recorded as a regulatory liability, which is amortized as incremental costs are incurred to operate and depreciate Consumers’ wind parks and to purchase RECs under renewable energy purchase agreements. Incremental costs represent costs incurred in excess of amounts recovered through the PSCR process. | |||||||||
Energy Optimization Plan: At December 31, 2014 and 2013, surcharges collected from customers to fund Consumers’ energy optimization plan exceeded Consumers’ spending. The associated regulatory liability is amortized as costs are incurred under Consumers’ energy optimization plan. | |||||||||
Power Supply Cost Recovery and Gas Cost Recovery | |||||||||
The PSCR and GCR ratemaking processes are designed to allow Consumers to recover all of its power supply and purchased natural gas costs if incurred under reasonable and prudent policies and practices. The MPSC reviews these costs, policies, and practices in annual plan and reconciliation proceedings. Consumers adjusts its PSCR and GCR billing charges monthly in order to minimize the underrecovery or overrecovery amount in the annual reconciliations. | |||||||||
Underrecoveries represent probable future revenues that will be recovered from customers and are included in accrued gas revenue on Consumers’ consolidated balance sheets. Overrecoveries represent previously collected revenues that will be refunded to customers and are included in accrued rate refunds on Consumers’ consolidated balance sheets. Presented in the following table are the assets and liabilities for PSCR and GCR underrecoveries and overrecoveries reflected on Consumers’ consolidated balance sheets: | |||||||||

PSCR Plans and Reconciliations: In May 2014, the MPSC issued an order in Consumers’ 2012 PSCR reconciliation, approving full recovery of $1.9 billion of power costs and authorizing Consumers to roll into its 2013 PSCR plan the underrecovery of $18 million. | |||||||||
Consumers submitted its 2013 PSCR plan to the MPSC in September 2012, and in accordance with its proposed plan, self-implemented the 2013 PSCR factor beginning in January 2013. In March 2014, Consumers filed its 2013 PSCR reconciliation, requesting full recovery of $1.9 billion of power costs and authorization to roll into its 2014 PSCR plan the overrecovery of $10 million. | |||||||||
Consumers submitted its 2014 PSCR plan to the MPSC in September 2013, and in accordance with its proposed plan, self-implemented the 2014 PSCR factor beginning in January 2014. Consumers’ power supply costs for 2014 were significantly higher than those projected in its 2014 PSCR plan due to severe winter weather during the three months ended March 31, 2014, as extreme cold weather and heavy snowfall inhibited the delivery and use of coal at Consumers’ coal-fueled generating units. Additionally, increases in natural gas prices raised the cost of electricity purchased from the MISO energy market as well as the cost of power generated at Consumers’ natural gas-fueled generating units. Consumers filed an amendment to its 2014 PSCR plan in March 2014, requesting approval to increase the 2014 PSCR factor. Consumers self-implemented the revised factor in July 2014. Consumers had a $6 million PSCR overrecovery at December 31, 2014. | |||||||||
GCR Plans and Reconciliations: In September 2014, the MPSC issued an order in Consumers’ 2012-2013 GCR reconciliation, approving full recovery of $0.9 billion in gas costs and authorizing Consumers to roll into its 2013-2014 GCR plan the underrecovery of $22 million. | |||||||||
The MPSC approved Consumers’ 2013-2014 GCR plan in July 2014, authorizing the 2013-2014 GCR factor that Consumers self-implemented beginning in April 2013. Due to the impact on natural gas prices of extended periods of colder-than-normal winter weather in Michigan and throughout the United States during the three months ended March 31, 2014, Consumers’ natural gas fuel costs for this period were significantly higher than those projected in its 2013-2014 GCR plan. As a result, Consumers calculated an $84 million underrecovery for the 2013-2014 GCR plan year. In the reconciliation it filed in June 2014, Consumers requested full recovery of $0.9 billion of gas costs and authorization to roll into its 2014-2015 GCR plan the underrecovery of $84 million. | |||||||||
Consumers submitted its 2014-2015 GCR plan in December 2013, and in accordance with its proposed plan, self-implemented the 2014-2015 GCR factor beginning in April 2014. Due to the significant underrecovery Consumers experienced during the 2013-2014 GCR plan year, Consumers filed an amendment to its 2014-2015 GCR plan in February 2014, requesting approval to increase the 2014-2015 GCR factor to be charged to customers. In May 2014, the MPSC issued an order authorizing Consumers to charge the increased factor to customers until the MPSC issues a final order in Consumers’ 2014-2015 GCR plan. Consumers had a $27 million GCR underrecovery recorded at December 31, 2014. | |||||||||

CMS Energy and Consumers are involved in various matters that give rise to contingent liabilities. Depending on the specific issues, the resolution of these contingencies could have a material effect on CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations. In their disclosures of these matters, CMS Energy and Consumers provide an estimate of the possible loss or range of loss when such an estimate can be made. Disclosures that state that CMS Energy or Consumers cannot predict the outcome of a matter indicate that they are unable to estimate a possible loss or range of loss for the matter. | |||||||||||||||||||||||
CMS Energy Contingencies | |||||||||||||||||||||||
Gas Index Price Reporting Litigation: CMS Energy, along with CMS MST, CMS Field Services, Cantera Natural Gas, Inc., and Cantera Gas Company, have been named as defendants in five class action lawsuits arising as a result of alleged inaccurate natural gas price reporting to publications that report trade information. Allegations include manipulation of NYMEX natural gas futures and options prices, price-fixing conspiracies, restraint of trade, and artificial inflation of natural gas retail prices in Kansas, Missouri, and Wisconsin. The following provides more detail on the cases in which CMS Energy or its affiliates remain as parties: | |||||||||||||||||||||||
· | In 2005, CMS Energy, CMS MST, and CMS Field Services were named as defendants in a putative class action filed in Kansas state court, Learjet, Inc., et al. v. Oneok, Inc., et al. The complaint alleges that during the putative class period, January 1, 2000 through October 31, 2002, the defendants engaged in a scheme to violate the Kansas Restraint of Trade Act. The plaintiffs are seeking statutory full consideration damages consisting of the full consideration paid by the plaintiffs for natural gas allegedly purchased from the defendants. | ||||||||||||||||||||||
· | In 2007, a class action complaint, Heartland Regional Medical Center, et al. v. Oneok, Inc. et al., was filed as a putative class action in Missouri state court alleging violations of Missouri antitrust laws. The defendants, including CMS Energy, CMS Field Services, and CMS MST, are alleged to have violated the Missouri antitrust law in connection with their natural gas reporting activities. The plaintiffs are seeking full consideration damages and treble damages. | ||||||||||||||||||||||
· | In 2006, a class action complaint, Arandell Corp., et al. v. XCEL Energy Inc., et al., was filed in Wisconsin state court on behalf of Wisconsin commercial entities that purchased natural gas between January 1, 2000 and October 31, 2002. The defendants, including CMS Energy, CMS ERM, and Cantera Gas Company, are alleged to have violated Wisconsin’s antitrust statute. The plaintiffs are seeking full consideration damages, plus exemplary damages and attorneys’ fees. | ||||||||||||||||||||||
· | In 2009, a class action complaint, Newpage Wisconsin System v. CMS ERM, et al., was filed in circuit court in Wood County, Wisconsin, against CMS Energy, CMS ERM, Cantera Gas Company, and others. The plaintiff is seeking full consideration damages, treble damages, costs, interest, and attorneys’ fees. | ||||||||||||||||||||||
· | In 2005, J.P. Morgan Trust Company, N.A., in its capacity as trustee of the FLI Liquidating Trust, filed an action in Kansas state court against CMS Energy, CMS MST, CMS Field Services, and others. The complaint alleges various claims under the Kansas Restraint of Trade Act. The plaintiff is seeking statutory full consideration damages for its purchases of natural gas in 2000 and 2001. | ||||||||||||||||||||||
After removal to federal court, all of the cases described above were transferred to the MDL. In 2010 and 2011, all claims against CMS Energy defendants in the MDL cases were dismissed based on FERC preemption. Plaintiffs filed appeals in all of the cases. The issues on appeal were whether the district court erred in dismissing the cases based on FERC preemption and denying the plaintiffs’ motions for leave to amend their complaints to add a federal Sherman Act antitrust claim. The plaintiffs did not appeal the dismissal of CMS Energy as a defendant in these cases, but other CMS Energy entities remain as defendants. | |||||||||||||||||||||||
In April 2013, the U.S. Court of Appeals for the Ninth Circuit reversed the MDL decision and remanded the case to the MDL judge for further proceedings. The appellate court found that FERC preemption does not apply under the facts of these cases. The appellate court affirmed the MDL court’s denial of leave to amend to add federal antitrust claims. | |||||||||||||||||||||||
In August 2013, the joint defense group in these cases, of which CMS Energy defendants are members, filed a petition with the U.S. Supreme Court in an attempt to overturn the decision of the U.S. Court of Appeals for the Ninth Circuit. In July 2014, the U.S. Supreme Court agreed to hear this case. Arguments were heard in early 2015 and an opinion is expected in the first half of 2015. | |||||||||||||||||||||||
These cases involve complex facts, a large number of similarly situated defendants with different factual positions, and multiple jurisdictions. Presently, any estimate of liability would be highly speculative; the amount of CMS Energy’s possible loss would be based on widely varying models previously untested in this context. If the outcome after appeals is unfavorable, these cases could have a material adverse impact on CMS Energy’s liquidity, financial condition, and results of operations. | |||||||||||||||||||||||
Bay Harbor: CMS Energy retained environmental remediation obligations for the collection and treatment of leachate, a liquid consisting of water and other substances, at Bay Harbor after selling its interests in the development in 2002. Leachate is produced when water enters into cement kiln dust piles left over from former cement plant operations at the site. In 2012, CMS Energy and the MDEQ finalized an agreement that established the final remedies and the future water quality criteria at the site. CMS Energy has completed all construction necessary to implement the remedies required by the agreement and will continue to maintain and operate a system to discharge treated leachate into Little Traverse Bay under an NPDES permit issued in 2010. This permit requires renewal every five years. | |||||||||||||||||||||||
Various claims have been brought against CMS Land or its affiliates, including CMS Energy, alleging environmental damage to property, loss of property value, insufficient disclosure of environmental matters, breach of agreement relating to access, or other matters. CMS Land and other parties have received a demand for payment from the EPA in the amount of $8 million, plus interest. The EPA is seeking recovery under CERCLA of response costs allegedly incurred at Bay Harbor. These costs exceed what was agreed to in a 2005 order between CMS Land and the EPA, and CMS Land has communicated to the EPA that it does not believe that this is a valid claim. In August 2014, the EPA indicated that it intends to pursue the claim. | |||||||||||||||||||||||
In September 2014, CMS Energy recorded a charge of $15 million to maintenance and other operating expenses to increase the remaining liability for Bay Harbor as a result of changed cost estimates based on recent experience. Factors leading to the increase included higher water treatment costs, more frequent trucking of water due to system limitations, and increased system maintenance costs. CMS Energy has recorded a cumulative charge related to Bay Harbor of $245 million, which includes accretion expense. At December 31, 2014, CMS Energy had a recorded liability of $62 million for its remaining obligations. CMS Energy calculated this liability based on discounted projected costs, using a discount rate of 4.34 percent and an inflation rate of one percent on annual operating and maintenance costs. The undiscounted amount of the remaining obligation is $80 million. CMS Energy expects to pay $8 million in 2015, $6 million in 2016, $5 million in 2017, $5 million in 2018, and $5 million in 2019, and the remaining amount thereafter on long-term liquid disposal and operating and maintenance costs. CMS Energy’s estimate of response activity costs and the timing of expenditures could change if there are changes in circumstances or assumptions used in calculating the liability. | |||||||||||||||||||||||
Although a liability for its present estimate of remaining response activity costs has been recorded, CMS Energy cannot predict the ultimate financial impact or outcome of this matter. | |||||||||||||||||||||||
Equatorial Guinea Tax Claim: In 2002, CMS Energy sold its oil, gas, and methanol investments in Equatorial Guinea. The government of Equatorial Guinea claims that CMS Energy owes $142 million in taxes, plus significant penalties and interest, in connection with the sale and may proceed to formal arbitration. CMS Energy has concluded that the government’s tax claim is without merit. CMS Energy is vigorously contesting the claim but cannot predict the financial impact or outcome of this matter. It is possible that the outcome of this matter could have a material adverse effect on CMS Energy’s liquidity, financial condition, and results of operations. | |||||||||||||||||||||||
Consumers Electric Utility Contingencies | |||||||||||||||||||||||
Electric Environmental Matters: Consumers’ operations are subject to environmental laws and regulations. Historically, Consumers has generally been able to recover, in customer rates, the costs to operate its facilities in compliance with these laws and regulations. | |||||||||||||||||||||||
Cleanup and Solid Waste: Consumers expects to incur remediation and other response activity costs at a number of sites under NREPA. Consumers believes that these costs should be recoverable in rates, but cannot guarantee that outcome. Consumers estimates that its liability for NREPA sites for which it can estimate a range of loss will be between $4 million and $6 million. At December 31, 2014, Consumers had a recorded liability of $4 million, the minimum amount in the range of its estimated probable NREPA liability. | |||||||||||||||||||||||
Consumers is a potentially responsible party at a number of contaminated sites administered under CERCLA. CERCLA liability is joint and several. In 2010, Consumers received official notification from the EPA that identified Consumers as a potentially responsible party for cleanup of PCBs at the Kalamazoo River CERCLA site. The notification claimed that the EPA has reason to believe that Consumers disposed of PCBs and arranged for the disposal and treatment of PCB-containing materials at portions of the site. In 2011, Consumers received a follow‑up letter from the EPA requesting that Consumers agree to participate in a removal action plan along with several other companies for an area of lower Portage Creek, which is connected to the Kalamazoo River. All parties, including Consumers, that were asked to participate in the removal action plan declined to accept liability. Until further information is received from the EPA, Consumers is unable to estimate a range of potential liability for cleanup of the river. | |||||||||||||||||||||||
Based on its experience, Consumers estimates that its share of the total liability for known CERCLA sites will be between $3 million and $9 million. Various factors, including the number of potentially responsible parties involved with each site, affect Consumers’ share of the total liability. At December 31, 2014, Consumers had a recorded liability of $3 million for its share of the total liability at these sites, the minimum amount in the range of its estimated probable CERCLA liability. | |||||||||||||||||||||||
The timing of payments related to Consumers’ remediation and other response activities at its CERCLA and NREPA sites is uncertain. Consumers periodically reviews these cost estimates. Any significant change in the underlying assumptions, such as an increase in the number of sites, different remediation techniques, the nature and extent of contamination, and legal and regulatory requirements, could affect its estimates of NREPA and CERCLA liability. | |||||||||||||||||||||||
Ludington PCB: In 1998, during routine maintenance activities, Consumers identified PCB as a component in certain paint, grout, and sealant materials at Ludington. Consumers removed and replaced part of the PCB material with non‑PCB material. Consumers has had several communications with the EPA regarding this matter. Consumers cannot predict the financial impact or outcome of this matter. | |||||||||||||||||||||||
Electric Utility Plant Air Permit Issues and Notices of Violation: In 2007, Consumers received an NOV/FOV from the EPA alleging that fourteen utility boilers exceeded the visible emission limits in their associated air permits. Consumers responded formally to the NOV/FOV, denying the allegations. In addition, in 2008, Consumers received an NOV for three of its coal-fueled facilities alleging, among other things, violations of NSR PSD regulations relating to ten projects from 1986 to 1998 purportedly subject to review under the NSR. Additionally, the EPA has alleged that some utilities have classified incorrectly major plant modifications as RMRR rather than seeking permits from the EPA or state regulatory agencies to modify their plants. Consumers responded to the information requests from the EPA on this subject in the past. | |||||||||||||||||||||||
In September 2014, Consumers reached a settlement in this matter with the EPA and the U.S. Department of Justice. Under the settlement, Consumers shall, among other things, install pollution control equipment at some of its coal-fueled electric generating plants and achieve certain emission rates for specific pollutants, surrender emission allowances, invest in $7.7 million of Environmental Mitigation Projects, retire or repower certain coal-fueled units, and pay a civil penalty of $2.75 million. Consumers has accrued an amount sufficient to cover the costs of the civil penalty and some of the Environmental Mitigation Projects. Consumers has recovered or expects that it would be able to recover some or all of the costs in rates, consistent with the recovery of other reasonable costs of complying with environmental laws and regulations, but cannot reasonably estimate the extent of additional cost recovery. The settlement, completed via consent decree, was finalized in November 2014. | |||||||||||||||||||||||
CCRs: In December 2014, the EPA issued a final rule regulating CCRs, such as coal ash, under the Resource Conservation and Recovery Act. The final rule will adopt non-hazardous waste standards for CCRs. The rule will add new requirements for groundwater monitoring, flood protection, storm water design, fugitive dust, and public disclosure of information. The rule will also require closure of non-compliant surface impoundments and landfills within approximately three years, with limited potential for extensions. The rule is expected to be published in early 2015. Consumers expects that planned capital expenditures will likely be accelerated to meet the compliance deadline, but is still evaluating the impacts of this rule. | |||||||||||||||||||||||
Renewable Energy Matters: In April 2013, a group of landowners filed a lawsuit in Mason County (Michigan) Circuit Court alleging, among other things, personal injury, loss of property value, and impacts to the use and enjoyment of their land as a result of the operations of Lake Winds® Energy Park. In October 2014, Consumers reached a settlement with a majority of the plaintiffs, and in January 2015, reached a settlement with the remaining plaintiffs, neither of which was material to Consumers. | |||||||||||||||||||||||
Consumers Gas Utility Contingencies | |||||||||||||||||||||||
Gas Environmental Matters: Consumers expects to incur remediation and other response activity costs at a number of sites under the NREPA. These sites include 23 former MGP facilities. Consumers operated the facilities on these sites for some part of their operating lives. For some of these sites, Consumers has no present ownership interest or may own only a portion of the original site. | |||||||||||||||||||||||
At December 31, 2014, Consumers had a recorded liability of $115 million for its remaining obligations for these sites. This amount represents the present value of long-term projected costs, using a discount rate of 2.57 percent and an inflation rate of 2.5 percent. The undiscounted amount of the remaining obligation is $131 million. Consumers expects to incur remediation and other response activity costs in each of the next five years as follows: | |||||||||||||||||||||||

Consumers periodically reviews these cost estimates. Any significant change in the underlying assumptions, such as an increase in the number of sites, changes in remediation techniques, or legal and regulatory requirements, could affect Consumers’ estimates of annual response activity costs and the MGP liability. | |||||||||||||||||||||||
Pursuant to orders issued by the MPSC, Consumers defers its MGP-related remediation costs and recovers them from its customers over a ten-year period. At December 31, 2014, Consumers had a regulatory asset of $147 million related to the MGP sites. | |||||||||||||||||||||||
Consumers estimates that its liability to perform remediation and other response activities at NREPA sites other than the MGP sites could reach $3 million. At December 31, 2014, Consumers had a recorded liability of less than $1 million, the minimum amount in the range of its estimated probable liability. | |||||||||||||||||||||||

The plaintiffs are seeking full consideration damages, plus exemplary damages and attorneys’ fees. | ||||||||||||||||||||||
· | In 2009, a class action complaint, Newpage Wisconsin System v. CMS ERM, et al., was filed in circuit court in Wood County, Wisconsin, against CMS Energy, CMS ERM, Cantera Gas Company, and others. The plaintiff is seeking full consideration damages, treble damages, costs, interest, and attorneys’ fees. | ||||||||||||||||||||||
· | In 2005, J.P. Morgan Trust Company, N.A., in its capacity as trustee of the FLI Liquidating Trust, filed an action in Kansas state court against CMS Energy, CMS MST, CMS Field Services, and others. The complaint alleges various claims under the Kansas Restraint of Trade Act. The plaintiff is seeking statutory full consideration damages for its purchases of natural gas in 2000 and 2001. | ||||||||||||||||||||||
After removal to federal court, all of the cases described above were transferred to the MDL. In 2010 and 2011, all claims against CMS Energy defendants in the MDL cases were dismissed based on FERC preemption. Plaintiffs filed appeals in all of the cases. The issues on appeal were whether the district court erred in dismissing the cases based on FERC preemption and denying the plaintiffs’ motions for leave to amend their complaints to add a federal Sherman Act antitrust claim. The plaintiffs did not appeal the dismissal of CMS Energy as a defendant in these cases, but other CMS Energy entities remain as defendants. | |||||||||||||||||||||||
In April 2013, the U.S. Court of Appeals for the Ninth Circuit reversed the MDL decision and remanded the case to the MDL judge for further proceedings. The appellate court found that FERC preemption does not apply under the facts of these cases. The appellate court affirmed the MDL court’s denial of leave to amend to add federal antitrust claims. | |||||||||||||||||||||||
In August 2013, the joint defense group in these cases, of which CMS Energy defendants are members, filed a petition with the U.S. Supreme Court in an attempt to overturn the decision of the U.S. Court of Appeals for the Ninth Circuit. In July 2014, the U.S. Supreme Court agreed to hear this case. Arguments were heard in early 2015 and an opinion is expected in the first half of 2015. | |||||||||||||||||||||||
These cases involve complex facts, a large number of similarly situated defendants with different factual positions, and multiple jurisdictions. Presently, any estimate of liability would be highly speculative; the amount of CMS Energy’s possible loss would be based on widely varying models previously untested in this context. If the outcome after appeals is unfavorable, these cases could have a material adverse impact on CMS Energy’s liquidity, financial condition, and results of operations. | |||||||||||||||||||||||
Bay Harbor: CMS Energy retained environmental remediation obligations for the collection and treatment of leachate, a liquid consisting of water and other substances, at Bay Harbor after selling its interests in the development in 2002. Leachate is produced when water enters into cement kiln dust piles left over from former cement plant operations at the site. In 2012, CMS Energy and the MDEQ finalized an agreement that established the final remedies and the future water quality criteria at the site. CMS Energy has completed all construction necessary to implement the remedies required by the agreement and will continue to maintain and operate a system to discharge treated leachate into Little Traverse Bay under an NPDES permit issued in 2010. This permit requires renewal every five years. | |||||||||||||||||||||||
Various claims have been brought against CMS Land or its affiliates, including CMS Energy, alleging environmental damage to property, loss of property value, insufficient disclosure of environmental matters, breach of agreement relating to access, or other matters. CMS Land and other parties have received a demand for payment from the EPA in the amount of $8 million, plus interest. The EPA is seeking recovery under CERCLA of response costs allegedly incurred at Bay Harbor. These costs exceed what was agreed to in a 2005 order between CMS Land and the EPA, and CMS Land has communicated to the EPA that it does not believe that this is a valid claim. In August 2014, the EPA indicated that it intends to pursue the claim. | |||||||||||||||||||||||
In September 2014, CMS Energy recorded a charge of $15 million to maintenance and other operating expenses to increase the remaining liability for Bay Harbor as a result of changed cost estimates based on recent experience. Factors leading to the increase included higher water treatment costs, more frequent trucking of water due to system limitations, and increased system maintenance costs. CMS Energy has recorded a cumulative charge related to Bay Harbor of $245 million, which includes accretion expense. At December 31, 2014, CMS Energy had a recorded liability of $62 million for its remaining obligations. CMS Energy calculated this liability based on discounted projected costs, using a discount rate of 4.34 percent and an inflation rate of one percent on annual operating and maintenance costs. The undiscounted amount of the remaining obligation is $80 million. CMS Energy expects to pay $8 million in 2015, $6 million in 2016, $5 million in 2017, $5 million in 2018, and $5 million in 2019, and the remaining amount thereafter on long-term liquid disposal and operating and maintenance costs. CMS Energy’s estimate of response activity costs and the timing of expenditures could change if there are changes in circumstances or assumptions used in calculating the liability. | |||||||||||||||||||||||
Although a liability for its present estimate of remaining response activity costs has been recorded, CMS Energy cannot predict the ultimate financial impact or outcome of this matter. | |||||||||||||||||||||||
Equatorial Guinea Tax Claim: In 2002, CMS Energy sold its oil, gas, and methanol investments in Equatorial Guinea. The government of Equatorial Guinea claims that CMS Energy owes $142 million in taxes, plus significant penalties and interest, in connection with the sale and may proceed to formal arbitration. CMS Energy has concluded that the government’s tax claim is without merit. CMS Energy is vigorously contesting the claim but cannot predict the financial impact or outcome of this matter. It is possible that the outcome of this matter could have a material adverse effect on CMS Energy’s liquidity, financial condition, and results of operations. | |||||||||||||||||||||||
Consumers Electric Utility Contingencies | |||||||||||||||||||||||
Electric Environmental Matters: Consumers’ operations are subject to environmental laws and regulations. Historically, Consumers has generally been able to recover, in customer rates, the costs to operate its facilities in compliance with these laws and regulations. | |||||||||||||||||||||||
Cleanup and Solid Waste: Consumers expects to incur remediation and other response activity costs at a number of sites under NREPA. Consumers believes that these costs should be recoverable in rates, but cannot guarantee that outcome. Consumers estimates that its liability for NREPA sites for which it can estimate a range of loss will be between $4 million and $6 million. At December 31, 2014, Consumers had a recorded liability of $4 million, the minimum amount in the range of its estimated probable NREPA liability. | |||||||||||||||||||||||
Consumers is a potentially responsible party at a number of contaminated sites administered under CERCLA. CERCLA liability is joint and several. In 2010, Consumers received official notification from the EPA that identified Consumers as a potentially responsible party for cleanup of PCBs at the Kalamazoo River CERCLA site. The notification claimed that the EPA has reason to believe that Consumers disposed of PCBs and arranged for the disposal and treatment of PCB-containing materials at portions of the site. In 2011, Consumers received a follow‑up letter from the EPA requesting that Consumers agree to participate in a removal action plan along with several other companies for an area of lower Portage Creek, which is connected to the Kalamazoo River. All parties, including Consumers, that were asked to participate in the removal action plan declined to accept liability. Until further information is received from the EPA, Consumers is unable to estimate a range of potential liability for cleanup of the river. | |||||||||||||||||||||||
Based on its experience, Consumers estimates that its share of the total liability for known CERCLA sites will be between $3 million and $9 million. Various factors, including the number of potentially responsible parties involved with each site, affect Consumers’ share of the total liability. At December 31, 2014, Consumers had a recorded liability of $3 million for its share of the total liability at these sites, the minimum amount in the range of its estimated probable CERCLA liability. | |||||||||||||||||||||||
The timing of payments related to Consumers’ remediation and other response activities at its CERCLA and NREPA sites is uncertain. Consumers periodically reviews these cost estimates. Any significant change in the underlying assumptions, such as an increase in the number of sites, different remediation techniques, the nature and extent of contamination, and legal and regulatory requirements, could affect its estimates of NREPA and CERCLA liability. | |||||||||||||||||||||||
Ludington PCB: In 1998, during routine maintenance activities, Consumers identified PCB as a component in certain paint, grout, and sealant materials at Ludington. Consumers removed and replaced part of the PCB material with non‑PCB material. Consumers has had several communications with the EPA regarding this matter. Consumers cannot predict the financial impact or outcome of this matter. | |||||||||||||||||||||||
Electric Utility Plant Air Permit Issues and Notices of Violation: In 2007, Consumers received an NOV/FOV from the EPA alleging that fourteen utility boilers exceeded the visible emission limits in their associated air permits. Consumers responded formally to the NOV/FOV, denying the allegations. In addition, in 2008, Consumers received an NOV for three of its coal-fueled facilities alleging, among other things, violations of NSR PSD regulations relating to ten projects from 1986 to 1998 purportedly subject to review under the NSR. Additionally, the EPA has alleged that some utilities have classified incorrectly major plant modifications as RMRR rather than seeking permits from the EPA or state regulatory agencies to modify their plants. Consumers responded to the information requests from the EPA on this subject in the past. | |||||||||||||||||||||||
In September 2014, Consumers reached a settlement in this matter with the EPA and the U.S. Department of Justice. Under the settlement, Consumers shall, among other things, install pollution control equipment at some of its coal-fueled electric generating plants and achieve certain emission rates for specific pollutants, surrender emission allowances, invest in $7.7 million of Environmental Mitigation Projects, retire or repower certain coal-fueled units, and pay a civil penalty of $2.75 million. Consumers has accrued an amount sufficient to cover the costs of the civil penalty and some of the Environmental Mitigation Projects. Consumers has recovered or expects that it would be able to recover some or all of the costs in rates, consistent with the recovery of other reasonable costs of complying with environmental laws and regulations, but cannot reasonably estimate the extent of additional cost recovery. The settlement, completed via consent decree, was finalized in November 2014. | |||||||||||||||||||||||
CCRs: In December 2014, the EPA issued a final rule regulating CCRs, such as coal ash, under the Resource Conservation and Recovery Act. The final rule will adopt non-hazardous waste standards for CCRs. The rule will add new requirements for groundwater monitoring, flood protection, storm water design, fugitive dust, and public disclosure of information. The rule will also require closure of non-compliant surface impoundments and landfills within approximately three years, with limited potential for extensions. The rule is expected to be published in early 2015. Consumers expects that planned capital expenditures will likely be accelerated to meet the compliance deadline, but is still evaluating the impacts of this rule. | |||||||||||||||||||||||
Renewable Energy Matters: In April 2013, a group of landowners filed a lawsuit in Mason County (Michigan) Circuit Court alleging, among other things, personal injury, loss of property value, and impacts to the use and enjoyment of their land as a result of the operations of Lake Winds® Energy Park. In October 2014, Consumers reached a settlement with a majority of the plaintiffs, and in January 2015, reached a settlement with the remaining plaintiffs, neither of which was material to Consumers. | |||||||||||||||||||||||
Consumers Gas Utility Contingencies | |||||||||||||||||||||||
Gas Environmental Matters: Consumers expects to incur remediation and other response activity costs at a number of sites under the NREPA. These sites include 23 former MGP facilities. Consumers operated the facilities on these sites for some part of their operating lives. For some of these sites, Consumers has no present ownership interest or may own only a portion of the original site. | |||||||||||||||||||||||
At December 31, 2014, Consumers had a recorded liability of $115 million for its remaining obligations for these sites. This amount represents the present value of long-term projected costs, using a discount rate of 2.57 percent and an inflation rate of 2.5 percent. The undiscounted amount of the remaining obligation is $131 million. Consumers expects to incur remediation and other response activity costs in each of the next five years as follows: | |||||||||||||||||||||||

Consumers periodically reviews these cost estimates. Any significant change in the underlying assumptions, such as an increase in the number of sites, changes in remediation techniques, or legal and regulatory requirements, could affect Consumers’ estimates of annual response activity costs and the MGP liability. | |||||||||||||||||||||||
Pursuant to orders issued by the MPSC, Consumers defers its MGP-related remediation costs and recovers them from its customers over a ten-year period. At December 31, 2014, Consumers had a regulatory asset of $147 million related to the MGP sites. | |||||||||||||||||||||||
Consumers estimates that its liability to perform remediation and other response activities at NREPA sites other than the MGP sites could reach $3 million. At December 31, 2014, Consumers had a recorded liability of less than $1 million, the minimum amount in the range of its estimated probable liability. | |||||||||||||||||||||||

CMS Energy, Consumers, and certain other subsidiaries of CMS Energy also enter into various agreements containing tax and other indemnity provisions for which they are unable to estimate the maximum potential obligation. These factors include unspecified exposure under certain agreements. CMS Energy and Consumers consider the likelihood that they would be required to perform or incur substantial losses related to these indemnities to be remote. | |||||||||||||||||||||||
Other Contingencies | |||||||||||||||||||||||
Other: In addition to the matters disclosed in this Note and Note 3, Regulatory Matters, there are certain other lawsuits and administrative proceedings before various courts and governmental agencies arising in the ordinary course of business to which CMS Energy, Consumers, and certain other subsidiaries of CMS Energy are parties. These other lawsuits and proceedings may involve personal injury, property damage, contracts, environmental matters, federal and state taxes, rates, licensing, employment, and other matters. Further, CMS Energy and Consumers occasionally self-report certain regulatory non‑compliance matters that may or may not eventually result in administrative proceedings. CMS Energy and Consumers believe that the outcome of any one of these proceedings will not have a material adverse effect on their consolidated results of operations, financial condition, or liquidity. | |||||||||||||||||||||||

Fair Value Measurements | 6:FAIR VALUE MEASUREMENTS | ||||||||||||||||
Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. When measuring fair value, CMS Energy and Consumers are required to incorporate all assumptions that market participants would use in pricing an asset or liability, including assumptions about risk. A fair value hierarchy prioritizes inputs used to measure fair value according to their observability in the market. The three levels of the fair value hierarchy are as follows: | |||||||||||||||||
· | Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities. | ||||||||||||||||
· | Level 2 inputs are observable, market-based inputs, other than Level 1 prices. Level 2 inputs may include quoted prices for similar assets or liabilities in active markets, quoted prices in inactive markets, and inputs derived from or corroborated by observable market data. | ||||||||||||||||
· | Level 3 inputs are unobservable inputs that reflect CMS Energy’s or Consumers’ own assumptions about how market participants would value their assets and liabilities. | ||||||||||||||||
To the extent possible, CMS Energy and Consumers use quoted market prices or other observable market pricing data in valuing assets and liabilities measured at fair value. If this information is unavailable, they use market-corroborated data or reasonable estimates about market participant assumptions. CMS Energy and Consumers classify fair value measurements within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement in its entirety. | |||||||||||||||||
Assets and Liabilities Measured at Fair Value on a Recurring Basis | |||||||||||||||||

Nonqualified Deferred Compensation Plan Assets and Liabilities: The nonqualified deferred compensation plan assets consist of mutual funds, which are valued using the daily quoted NAVs that are publicly available and are the basis for transactions to buy or sell shares in each fund. CMS Energy and Consumers value their nonqualified deferred compensation plan liabilities based on the fair values of the plan assets, as they reflect what is owed to the plan participants in accordance with their investment elections.

DB SERP Assets: CMS Energy and Consumers value their DB SERP assets using a market approach that incorporates quoted market prices. The DB SERP cash equivalents consist of a money market fund with daily liquidity. The DB SERP invests in mutual funds that hold primarily fixed-income instruments of varying maturities. In order to meet their investment objectives, the funds hold investment-grade debt securities, and may invest a portion of their assets in high-yield securities, foreign debt, and derivative instruments. CMS Energy and Consumers value these funds using the daily quoted NAVs that are publicly available and are the basis for transactions to buy or sell shares in each fund. CMS Energy and Consumers report their DB SERP assets in other non‑current assets on their consolidated balance sheets.

Derivative Instruments: CMS Energy and Consumers value their derivative instruments using either a market approach that incorporates information from market transactions, or an income approach that discounts future expected cash flows to a present value amount. CMS Energy values its exchange-traded derivative contracts based on Level 1 quoted prices and values other derivatives using Level 2 inputs, which include commodity forward prices and credit risk factors. CMS Energy and Consumers have classified certain derivatives as Level 3 since the fair value measurements incorporate assumptions that cannot be observed or confirmed through market transactions. | |||||||||||||||||
The majority of derivatives classified as Level 3 are FTRs held by Consumers. Due to the lack of quoted pricing information, Consumers determines the fair value of its FTRs based on Consumers’ average historical settlements. | |||||||||||||||||

Fair Value Measurements | 6:FAIR VALUE MEASUREMENTS | ||||||||||||||||
Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. When measuring fair value, CMS Energy and Consumers are required to incorporate all assumptions that market participants would use in pricing an asset or liability, including assumptions about risk. A fair value hierarchy prioritizes inputs used to measure fair value according to their observability in the market. The three levels of the fair value hierarchy are as follows: | |||||||||||||||||
· | Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities. | ||||||||||||||||
· | Level 2 inputs are observable, market-based inputs, other than Level 1 prices. Level 2 inputs may include quoted prices for similar assets or liabilities in active markets, quoted prices in inactive markets, and inputs derived from or corroborated by observable market data. | ||||||||||||||||
· | Level 3 inputs are unobservable inputs that reflect CMS Energy’s or Consumers’ own assumptions about how market participants would value their assets and liabilities. | ||||||||||||||||
To the extent possible, CMS Energy and Consumers use quoted market prices or other observable market pricing data in valuing assets and liabilities measured at fair value. If this information is unavailable, they use market-corroborated data or reasonable estimates about market participant assumptions. CMS Energy and Consumers classify fair value measurements within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement in its entirety. | |||||||||||||||||

EnerBank notes receivable are unsecured consumer installment loans for financing home improvements. EnerBank records its notes receivable at cost, less allowance for loan losses. At December 31, 2014, $41 million of notes receivable were reclassified to held for sale; the fair value of notes receivable held for sale exceeded their carrying value. These notes are expected to be sold in 2015. | ||||||||
The allowance for loan losses is a valuation allowance to reflect estimated credit losses. The allowance is increased by the provision for loan losses and decreased by loan charge-offs net of recoveries. Management estimates the allowance balance required by taking into consideration historical loan loss experience, the nature and volume of the portfolio, economic conditions, and other factors. Loan losses are charged against the allowance when the loss is confirmed, but no later than the point at which a loan becomes 120 days past due. | ||||||||

1 | In 2007, Consumers sold Palisades to Entergy and entered into a 15-year PPA to buy all of the capacity and energy then capable of being produced by Palisades. Consumers has continuing involvement with Palisades through security provided to Entergy for Consumers’ PPA obligation and other arrangements. Because of these ongoing arrangements, Consumers accounted for the transaction as a financing of Palisades and not a sale. Accordingly, no gain on the sale of Palisades was recognized on the consolidated statements of income. Consumers accounted for the remaining non-real-estate assets and liabilities associated with the transaction as a sale. | ||||||||||
Palisades remains on Consumers’ consolidated balance sheets and Consumers continues to depreciate it. Consumers recorded the related proceeds as a finance obligation with payments recorded to interest expense and the finance obligation based on the amortization of the obligation over the life of the Palisades PPA. The value of the finance obligation was determined based on an allocation of the transaction proceeds to the fair values of the net assets sold and fair value of the plant asset under the financing. Total amortization and interest charges under the financing were $19 million for the year ended December 31, 2014 and $20 million for each of the years ended December 31, 2013 and December 31, 2012. | |||||||||||

Consumers has capital leases for gas transportation pipelines to the D.E. Karn generating complex and Zeeland. The capital lease for the gas transportation pipeline into the D.E. Karn generating complex has a term of 15 years with a provision to extend the contract from month to month. The remaining term of the contract was seven years at December 31, 2014. The capital lease for the gas transportation pipeline to Zeeland has a term of five years with a renewal provision of an additional five years at the end of the contract. The remaining term of the contract was three years at December 31, 2014. The remaining terms of Consumers’ long-term PPAs accounted for as leases range between one and 18 years.

1 | In 2007, Consumers sold Palisades to Entergy and entered into a 15-year PPA to buy all of the capacity and energy then capable of being produced by Palisades. Consumers has continuing involvement with Palisades through security provided to Entergy for Consumers’ PPA obligation and other arrangements. Because of these ongoing arrangements, Consumers accounted for the transaction as a financing of Palisades and not a sale. Accordingly, no gain on the sale of Palisades was recognized on the consolidated statements of income. Consumers accounted for the remaining non-real-estate assets and liabilities associated with the transaction as a sale. | ||||||||||
Palisades remains on Consumers’ consolidated balance sheets and Consumers continues to depreciate it. Consumers recorded the related proceeds as a finance obligation with payments recorded to interest expense and the finance obligation based on the amortization of the obligation over the life of the Palisades PPA. The value of the finance obligation was determined based on an allocation of the transaction proceeds to the fair values of the net assets sold and fair value of the plant asset under the financing. Total amortization and interest charges under the financing were $19 million for the year ended December 31, 2014 and $20 million for each of the years ended December 31, 2013 and December 31, 2012. | |||||||||||

DC SERP: On April 1, 2006, CMS Energy and Consumers implemented a DC SERP and froze further new participation in the DB SERP. The DC SERP provides participants benefits ranging from 5 percent to 15 percent of total compensation. The DC SERP requires a minimum of five years of participation before vesting. CMS Energy’s and Consumers’ contributions to the plan, if any, are placed in a grantor trust. For CMS Energy and Consumers, trust assets were $2 million at December 31, 2014 and $1 million at December 31, 2013. DC SERP assets are included in other non‑current assets on CMS Energy’s and Consumers’ consolidated balance sheets. CMS Energy’s and Consumers’ DC SERP expense was less than $1 million for each of the years ended December 31, 2014, 2013, and 2012. | ||||||||||||||||||||||
401(k) Plan: The 401(k) plan employer match equals 60 percent of eligible contributions up to the first six percent of an employee’s wages.

1 | The discount rate reflects the rate at which benefits could be effectively settled and is equal to the equivalent single rate resulting from a yield curve analysis. This analysis incorporated the projected benefit payments specific to CMS Energy’s and Consumers’ DB Pension Plan and OPEB Plan and the yields on high quality corporate bonds rated Aa or better. | |||||||||||||||||||||
2 | The mortality assumption for 2014 for benefit obligations was based on the new RP‑2014 mortality table, with projection scale MP‑2014. The mortality assumption for 2013 and 2012 was based on the RP‑2000 mortality tables with projection of future mortality improvements using Scale AA, which aligned with the IRS prescriptions for cash funding valuations under the Pension Protection Act of 2006. The mortality assumption for all three years for net periodic benefit cost was based on the RP‑2000 mortality table. | |||||||||||||||||||||
3 | CMS Energy and Consumers determined the long-term rate of return using historical market returns, the present and expected future economic environment, the capital market principles of risk and return, and the expert opinions of individuals and firms with financial market knowledge. CMS Energy and Consumers considered the asset allocation of the portfolio in forecasting the future expected total return of the portfolio. The goal was to determine a long-term rate of return that could be incorporated into the planning of future cash flow requirements in conjunction with the change in the liability. Annually, CMS Energy and Consumers review for reasonableness and appropriateness the forecasted returns for various classes of assets used to construct an expected return model. CMS Energy’s and Consumers’ expected long-term rate of return on DB Pension Plan assets was 7.5 percent in 2014. The actual return on DB Pension Plan assets was 7.4 percent in 2014, 12.5 percent in 2013, and 14.1 percent in 2012. | |||||||||||||||||||||

CMS Energy and Consumers amortize net gains and losses in excess of ten percent of the greater of the PBO or the MRV over the average remaining service period. The estimated period of amortization of gains and losses for CMS Energy and Consumers was ten years for the DB Pension Plan for the years ended December 31, 2014 and 2013 and 11 years for the DB Pension Plan for the year ended December 31, 2012 and 13 years for OPEB for the years ended December 31, 2014, 2013, and 2012. Prior service cost (credit) amortization is established in the year in which the prior service cost (credit) first occurred, and is based on the same amortization period for all future years until the prior service cost (credit) is fully amortized. CMS Energy and Consumers had a new prior service credit for OPEB in 2013. The estimated period of amortization of this new prior service credit for CMS Energy and Consumers is ten years. | ||||||||||||||||||||||

2 | Plan amendments resulted from changing the Medicare drug program provided through the OPEB Plan from an employer-sponsored prescription drug plan with a retiree drug subsidy to an EGWP that began on January 1, 2015, and from certain benefit changes to the OPEB Plan, to begin on January 1, 2016. | |||||||||||||||||||||
3 | CMS Energy received payments of $4 million in 2014 and $5 million in each of 2013 and 2012 for the Medicare Part D subsidies. Consumers received payments of $4 million in each of 2014 and 2013 and $5 million in 2012 for the Medicare Part D subsidies. The Medicare Part D subsidy payments are used to pay OPEB Plan benefits. | |||||||||||||||||||||
As part of the annual measurement of benefit obligations, CMS Energy recorded an actuarial loss at December 31, 2014 of $458 million for the DB Pension Plan and $230 million for the OPEB Plan. Consumers recorded an actuarial loss at December 31, 2014 of $223 million for the OPEB Plan. Recognition of these actuarial losses at December 31, 2014 increased CMS Energy’s and Consumers’ benefit obligations and decreased the funded status of the plans. The changes were primarily the result of lowering the discount rates used in calculating the plans’ obligation and using the RP‑2014 mortality table. | ||||||||||||||||||||||

Cash and Short-Term Investments: Cash and short-term investments consist of money market funds with daily liquidity. | ||||||||||||||||||||||
U.S. Government and Agencies Securities: U.S. government and agencies securities consist of U.S. Treasury notes and other debt securities backed by the U.S. government and related agencies. These securities were valued based on quoted market prices. | ||||||||||||||||||||||
Corporate Debt: Corporate debt investments consisted of investment grade bonds of U.S. issuers from diverse industries. These securities are valued based on quoted market prices, when available, or yields presently available on comparable securities of issuers with similar credit ratings. | ||||||||||||||||||||||
State and Municipal Bonds: State and municipal bonds were valued using a matrix-pricing model that incorporates Level 2 market-based information. The fair value of the bonds was derived from various observable inputs, including benchmark yields, reported securities trades, broker/dealer quotes, bond ratings, and general information on market movements for investment grade state and municipal securities normally considered by market participants when pricing such debt securities. | ||||||||||||||||||||||
Foreign Corporate Bonds: Foreign corporate debt securities were valued based on quoted market prices, when available, or on yields available on comparable securities of issuers with similar credit ratings. | ||||||||||||||||||||||
Common Stocks: Common stocks in the OPEB Plan consist of equity securities with low transaction costs that were actively managed and tracked by the S&P 500 Index. These securities were valued at their quoted closing prices. | ||||||||||||||||||||||
Mutual Funds: Mutual funds represent shares in registered investment companies that are priced based on the daily quoted NAVs that are publicly available and are the basis for transactions to buy or sell shares in the funds. | ||||||||||||||||||||||
Pooled Funds: Pooled funds include both common and collective trust funds as well as special funds that contain only employee benefit plan assets from two or more unrelated benefit plans. Presented in the following table are the investment components of these funds: | ||||||||||||||||||||||

CMS Energy’s target asset allocation for DB Pension Plan assets is 50 percent equity, 30 percent fixed income, and 20 percent alternative-strategy investments. This target asset allocation is expected to continue to maximize the long-term return on plan assets, while maintaining a prudent level of risk. The level of acceptable risk is a function of the liabilities of the plan. Equity investments are diversified mostly across the S&P 500 Index, with lesser allocations to the S&P MidCap and SmallCap Indexes and Foreign Equity Funds. Fixed-income investments are diversified across investment grade instruments of government and corporate issuers as well as high-yield and global bond funds. Alternative strategies are diversified across absolute return investment approaches and global tactical asset allocation. CMS Energy and Consumers use annual liability measurements, quarterly portfolio reviews, and periodic asset/liability studies to evaluate the need for adjustments to the portfolio allocation. | ||||||||||||||||||||||
CMS Energy and Consumers established union and non‑union VEBA trusts to fund their future retiree health and life insurance benefits. These trusts are funded through the ratemaking process for Consumers and through direct contributions from the non‑utility subsidiaries. CMS Energy’s and Consumers’ target asset allocation for these trusts is 50 percent equity, 20 percent fixed income, and 30 percent alternative-strategy investments. CMS Energy and Consumers plan to adjust their target asset allocation in 2015 to 50 percent equity, 25 percent fixed income, and 25 percent alternative strategy investments. This target allocation is expected to continue to maximize the long-term return on plan assets, while maintaining a prudent level of risk. The level of acceptable risk is a function of the liabilities of the plan. Equity investments are diversified mostly across the S&P 500 Index, with lesser allocations to the S&P SmallCap Index and Foreign Equity Funds.

Contributions comprise required amounts and discretionary contributions. Actual future contributions will depend on future investment performance, discount rates, and various factors related to the DB Pension Plan and OPEB Plan participants. Following amendments to the OPEB Plan in July 2013, Consumers’ OPEB costs decreased substantially and, as a result, the OPEB Plan was fully funded at December 31, 2013. In May 2014, Consumers filed an application with the MPSC requesting approval to suspend contributions to Consumers’ OPEB Plan during 2014 and 2015 if the OPEB Plan continued to be fully funded. Consumers’ electric and gas rates still reflect the higher OPEB costs, and previous MPSC orders required Consumers to contribute to the OPEB Plan the associated amount collected in rates annually. | ||||||||||||||||||||||
In September 2014, the MPSC approved a settlement agreement addressing Consumers’ OPEB Plan funding application. Under the settlement agreement, Consumers contributed $25 million to the plan in 2014 and will contribute $29 million in February 2015. Consumers will then suspend further contributions until the MPSC determines funding requirements in future general rate cases. | ||||||||||||||||||||||

DC SERP: On April 1, 2006, CMS Energy and Consumers implemented a DC SERP and froze further new participation in the DB SERP. The DC SERP provides participants benefits ranging from 5 percent to 15 percent of total compensation. The DC SERP requires a minimum of five years of participation before vesting. CMS Energy’s and Consumers’ contributions to the plan, if any, are placed in a grantor trust. For CMS Energy and Consumers, trust assets were $2 million at December 31, 2014 and $1 million at December 31, 2013. DC SERP assets are included in other non‑current assets on CMS Energy’s and Consumers’ consolidated balance sheets. CMS Energy’s and Consumers’ DC SERP expense was less than $1 million for each of the years ended December 31, 2014, 2013, and 2012. | ||||||||||||||||||||||
401(k) Plan: The 401(k) plan employer match equals 60 percent of eligible contributions up to the first six percent of an employee’s wages. The total 401(k) plan cost for CMS Energy, including Consumers, and for Consumers was $18 million for the year ended December 31, 2014, $17 million for the year ended December 31, 2013, and $16 million for the year ended December 31, 2012. | ||||||||||||||||||||||
OPEB Plan: Participants in the OPEB Plan include all regular full-time employees covered by the employee health care plan on the day before retirement from either CMS Energy or Consumers at age 55 or older with at least ten full years of applicable continuous service. Regular full-time employees who qualify for DB Pension Plan disability retirement and have 15 years of applicable continuous service may also participate in the OPEB Plan. Retiree health care costs were based on the assumption that costs would increase 6.5 percent in 2015 and 2014. The rate of increase was assumed to decline to 4.75 percent by 2024 and thereafter. | ||||||||||||||||||||||

1 | The discount rate reflects the rate at which benefits could be effectively settled and is equal to the equivalent single rate resulting from a yield curve analysis. This analysis incorporated the projected benefit payments specific to CMS Energy’s and Consumers’ DB Pension Plan and OPEB Plan and the yields on high quality corporate bonds rated Aa or better. | |||||||||||||||||||||
2 | The mortality assumption for 2014 for benefit obligations was based on the new RP‑2014 mortality table, with projection scale MP‑2014. The mortality assumption for 2013 and 2012 was based on the RP‑2000 mortality tables with projection of future mortality improvements using Scale AA, which aligned with the IRS prescriptions for cash funding valuations under the Pension Protection Act of 2006. The mortality assumption for all three years for net periodic benefit cost was based on the RP‑2000 mortality table. | |||||||||||||||||||||
3 | CMS Energy and Consumers determined the long-term rate of return using historical market returns, the present and expected future economic environment, the capital market principles of risk and return, and the expert opinions of individuals and firms with financial market knowledge. CMS Energy and Consumers considered the asset allocation of the portfolio in forecasting the future expected total return of the portfolio. The goal was to determine a long-term rate of return that could be incorporated into the planning of future cash flow requirements in conjunction with the change in the liability. Annually, CMS Energy and Consumers review for reasonableness and appropriateness the forecasted returns for various classes of assets used to construct an expected return model. CMS Energy’s and Consumers’ expected long-term rate of return on DB Pension Plan assets was 7.5 percent in 2014. The actual return on DB Pension Plan assets was 7.4 percent in 2014, 12.5 percent in 2013, and 14.1 percent in 2012. | |||||||||||||||||||||

CMS Energy and Consumers amortize net gains and losses in excess of ten percent of the greater of the PBO or the MRV over the average remaining service period. The estimated period of amortization of gains and losses for CMS Energy and Consumers was ten years for the DB Pension Plan for the years ended December 31, 2014 and 2013 and 11 years for the DB Pension Plan for the year ended December 31, 2012 and 13 years for OPEB for the years ended December 31, 2014, 2013, and 2012. Prior service cost (credit) amortization is established in the year in which the prior service cost (credit) first occurred, and is based on the same amortization period for all future years until the prior service cost (credit) is fully amortized. CMS Energy and Consumers had a new prior service credit for OPEB in 2013. The estimated period of amortization of this new prior service credit for CMS Energy and Consumers is ten years. | ||||||||||||||||||||||

2 | Plan amendments resulted from changing the Medicare drug program provided through the OPEB Plan from an employer-sponsored prescription drug plan with a retiree drug subsidy to an EGWP that began on January 1, 2015, and from certain benefit changes to the OPEB Plan, to begin on January 1, 2016. | |||||||||||||||||||||
3 | CMS Energy received payments of $4 million in 2014 and $5 million in each of 2013 and 2012 for the Medicare Part D subsidies. Consumers received payments of $4 million in each of 2014 and 2013 and $5 million in 2012 for the Medicare Part D subsidies.

As part of the annual measurement of benefit obligations, CMS Energy recorded an actuarial loss at December 31, 2014 of $458 million for the DB Pension Plan and $230 million for the OPEB Plan. Consumers recorded an actuarial loss at December 31, 2014 of $223 million for the OPEB Plan. Recognition of these actuarial losses at December 31, 2014 increased CMS Energy’s and Consumers’ benefit obligations and decreased the funded status of the plans. The changes were primarily the result of lowering the discount rates used in calculating the plans’ obligation and using the RP‑2014 mortality table. | ||||||||||||||||||||||

CMS Energy’s target asset allocation for DB Pension Plan assets is 50 percent equity, 30 percent fixed income, and 20 percent alternative-strategy investments. This target asset allocation is expected to continue to maximize the long-term return on plan assets, while maintaining a prudent level of risk. The level of acceptable risk is a function of the liabilities of the plan. Equity investments are diversified mostly across the S&P 500 Index, with lesser allocations to the S&P MidCap and SmallCap Indexes and Foreign Equity Funds. Fixed-income investments are diversified across investment grade instruments of government and corporate issuers as well as high-yield and global bond funds. Alternative strategies are diversified across absolute return investment approaches and global tactical asset allocation. CMS Energy and Consumers use annual liability measurements, quarterly portfolio reviews, and periodic asset/liability studies to evaluate the need for adjustments to the portfolio allocation. | ||||||||||||||||||||||
CMS Energy and Consumers established union and non‑union VEBA trusts to fund their future retiree health and life insurance benefits. These trusts are funded through the ratemaking process for Consumers and through direct contributions from the non‑utility subsidiaries. CMS Energy’s and Consumers’ target asset allocation for these trusts is 50 percent equity, 20 percent fixed income, and 30 percent alternative-strategy investments. CMS Energy and Consumers plan to adjust their target asset allocation in 2015 to 50 percent equity, 25 percent fixed income, and 25 percent alternative strategy investments. This target allocation is expected to continue to maximize the long-term return on plan assets, while maintaining a prudent level of risk. The level of acceptable risk is a function of the liabilities of the plan.

Contributions comprise required amounts and discretionary contributions. Actual future contributions will depend on future investment performance, discount rates, and various factors related to the DB Pension Plan and OPEB Plan participants. Following amendments to the OPEB Plan in July 2013, Consumers’ OPEB costs decreased substantially and, as a result, the OPEB Plan was fully funded at December 31, 2013. In May 2014, Consumers filed an application with the MPSC requesting approval to suspend contributions to Consumers’ OPEB Plan during 2014 and 2015 if the OPEB Plan continued to be fully funded. Consumers’ electric and gas rates still reflect the higher OPEB costs, and previous MPSC orders required Consumers to contribute to the OPEB Plan the associated amount collected in rates annually. | ||||||||||||||||||||||
In September 2014, the MPSC approved a settlement agreement addressing Consumers’ OPEB Plan funding application. Under the settlement agreement, Consumers contributed $25 million to the plan in 2014 and will contribute $29 million in February 2015. Consumers will then suspend further contributions until the MPSC determines funding requirements in future general rate cases. | ||||||||||||||||||||||

In lieu of cash dividend payments, however, the dividends on performance-based and market-based restricted stock are paid in restricted shares equal to the value of the dividends. These additional restricted shares are subject to the same vesting conditions as the underlying restricted stock shares. | |||||||||||||
Market-based restricted stock vesting is generally contingent on meeting a three-year service requirement and on a market condition. The market condition is based on a comparison of CMS Energy’s total shareholder return with the median total shareholder return of a peer group over the same three-year period. Performance-based restricted stock vesting is contingent on meeting at least a 36‑month service requirement and a performance condition. The performance condition is based on CMS Energy’s EPS growth relative to a peer group over a three-year period. The awards granted in 2014 require a 38‑month service period. Depending on the outcome of the market condition or the performance condition, a recipient may earn a total award ranging from zero to 200 percent of the initial grant. Time-lapse restricted stock generally vests after a service period of three years. | |||||||||||||
All restricted stock awards vest fully upon death. Upon a change of control of CMS Energy or termination under an officer separation agreement, restricted stock awards will vest in accordance with specific officer agreements. If stated in the award, for restricted stock recipients who terminate employment due to retirement or disability, a pro-rata portion of the award equal to the portion of the service period served between the award grant date and the employee’s termination date will vest upon termination, with any market-based award also contingent upon the outcome of the market condition and any performance-based award contingent upon the outcome of the performance condition. The remaining portion of the awards will be forfeited. Restricted shares are forfeited fully if employment terminates for any other reason or if the minimum service requirements are not met, as described in the award document. | |||||||||||||
The PISP also allows for restricted common stock units, unrestricted common stock, stock options, stock appreciation rights, phantom shares, performance units, and incentive options, none of which was granted in 2014, 2013, or 2012. | |||||||||||||
Shares awarded or subject to stock options, phantom shares, or performance units may not exceed 6.5 million shares from June 2014 through May 2024, nor may such awards to any recipient exceed 500,000 shares in any calendar year. CMS Energy and Consumers may issue awards of up to 6,405,833 shares of common stock under the PISP at December 31, 2014. Shares for which payment or exercise is in cash, as well as shares that expire, terminate, or are cancelled or forfeited, may be awarded or granted again under the PISP. | |||||||||||||

CMS Energy and Consumers charge the fair value of the awards to expense over the required service period. For performance-based awards, CMS Energy and Consumers estimate the number of shares expected to vest at the end of the performance period based on the probable achievement of the performance objective. Performance-based and market-based restricted stock awards have graded vesting features for retirement-eligible employees, and CMS Energy and Consumers recognize expense for those awards on a graded vesting schedule over the required service period. Expense for performance-based and market-based restricted stock awards for non‑retirement-eligible employees and time-lapse awards is recognized on a straight-line basis over the required service period. | |||||||||||||
The fair value of performance-based and time-lapse restricted stock is based on the price of CMS Energy’s common stock on the grant date. The fair value of market-based restricted stock awards is calculated on the grant date using a Monte Carlo simulation. CMS Energy and Consumers base expected volatilities on the historical volatility of the price of CMS Energy common stock. The risk-free rate for valuation of the market-based restricted stock awards was based on the three-year U.S. Treasury yield at the award grant date. | |||||||||||||

Since CMS Energy has utilized tax loss carryforwards, CMS Energy was unable to realize excess federal tax benefits upon vesting of restricted stock. Therefore, CMS Energy did not recognize the related excess federal tax benefits in equity.

Prior to 2014, Consumers recognized the income tax benefits associated with the removal costs of plant placed in service before 1993 as payments were made and the tax benefits were flowed through to customers. In September 2013, the MPSC issued an order authorizing Consumers to flow through to customers the income tax benefits on a straight-line basis over an accelerated period. This new regulatory treatment, which Consumers implemented in January 2014, will accelerate the return of $209 million of income tax benefits over five years to electric customers and $260 million of income tax benefits over 12 years to gas customers. For the year ended December 31, 2014, this new treatment reduced Consumers’ income tax expense by $39 million. | ||||||||||||||

Prior to 2014, Consumers recognized the income tax benefits associated with the removal costs of plant placed in service before 1993 as payments were made and the tax benefits were flowed through to customers. In September 2013, the MPSC issued an order authorizing Consumers to flow through to customers the income tax benefits on a straight-line basis over an accelerated period. This new regulatory treatment, which Consumers implemented in January 2014, will accelerate the return of $209 million of income tax benefits over five years to electric customers and $260 million of income tax benefits over 12 years to gas customers. For the year ended December 31, 2014, this new treatment reduced Consumers’ income tax expense by $39 million. | ||||||||||||||

Deferred tax assets and liabilities are recognized for the estimated future tax effect of temporary differences between the tax basis of assets or liabilities and the reported amounts on CMS Energy’s and Consumers’ consolidated financial statements. Deferred tax assets and liabilities are classified as current or non‑current according to the classification of the related assets or liabilities. Deferred tax assets and liabilities not related to assets or liabilities are classified according to the expected reversal date of the temporary differences. | ||||||||||||||

CMS Energy has provided a valuation allowance of $1 million for the local tax loss carryforward, and a valuation allowance of $1 million for the state capital loss carryforward. Consumers has provided a valuation allowance of $1 million for the state capital loss carryforward. CMS Energy and Consumers expect to utilize fully tax loss and credit carryforwards for which no valuation has been provided.

If recognized, all of these uncertain tax benefits would affect CMS Energy’s and Consumers’ annual effective tax rates in future years. | ||||||||||||||
CMS Energy and Consumers recognize accrued interest and penalties, where applicable, as part of income tax expense. CMS Energy, including Consumers, recognized no interest or penalties for the years ended December 31, 2014, 2013, or 2012. | ||||||||||||||
In April 2014, the IRS completed its audit of the federal income tax returns of CMS Energy and its subsidiaries for 2010 and 2011. The audit resulted in no significant adjustments to CMS Energy’s or Consumers’ taxable income or income tax expense. | ||||||||||||||
CMS Energy’s federal income tax returns for 2012 and subsequent years remain subject to examination by the IRS. CMS Energy’s MCIT and MBT returns for 2008 and subsequent years remain subject to examination by the State of Michigan. | ||||||||||||||
The amount of income taxes paid is subject to ongoing audits by federal, state, local, and foreign tax authorities, which can result in proposed assessments. CMS Energy’s and Consumers’ estimate of the potential outcome for any uncertain tax issue is highly judgmental. CMS Energy and Consumers believe that their accrued tax liabilities at December 31, 2014 were adequate for all years. | ||||||||||||||

Contingently Convertible Securities | |||||||||||
In June 2014, CMS Energy redeemed its remaining contingently convertible securities. For the periods those securities were outstanding, they diluted EPS to the extent that the conversion value of the securities, which was based on the average market price of CMS Energy common stock, exceeded their principal value. For additional details regarding the contingently convertible securities, see Note 5, Financings and Capitalization. | |||||||||||
Non‑vested Stock Awards | |||||||||||
CMS Energy’s non‑vested stock awards are composed of participating and non‑participating securities. The participating securities accrue cash dividends when common stockholders receive dividends. Since the recipient is not required to return the dividends to CMS Energy if the recipient forfeits the award, the non‑vested stock awards are considered participating securities. As such, the participating non‑vested stock awards were included in the computation of basic EPS. The non‑participating securities accrue stock dividends that vest concurrently with the stock award. If the recipient forfeits the award, the stock dividends accrued on the non‑participating securities are also forfeited. Accordingly, the non‑participating awards and stock dividends were included in the computation of diluted EPS, but not basic EPS. | |||||||||||

Variable Interest Entities [Abstract] | ||||||
Variable Interest Entities | 19:VARIABLE INTEREST ENTITIES | |||||
CMS Energy has variable interests in T.E.S. Filer City, Grayling, and Genesee. CMS Energy is not the primary beneficiary of any of these partnerships because power is shared among unrelated parties, and no one party has the power to direct activities, such as operations and maintenance, plant dispatch, and fuel strategy, that most significantly impact the entities’ economic performance. The partners must agree on all major decisions for each of the partnerships. | ||||||
Presented in the following table is information about these partnerships: | ||||||
Name (Ownership Interest) | Nature of the Entity | Financing of Partnership | ||||
T.E.S. Filer City (50%) | Coal-fueled power generator | Non-recourse long-term debt that matured in | ||||
December 2007. | ||||||
Grayling (50%) | Wood waste-fueled power generator | Sale of revenue bonds that were retired in | ||||
March 2012. | ||||||
Genesee (50%) | Wood waste-fueled power generator | Sale of revenue bonds that mature in 2021 and bear interest at fixed rates. The debt is non-recourse to the partners and secured by a CMS Energy guarantee capped at $3 million annually. | ||||
CMS Energy has operating and management contracts with Grayling and Genesee, and Consumers is the primary purchaser of power from each partnership through long-term PPAs. Consumers also has reduced dispatch agreements with Grayling and Genesee, which allow these facilities to be dispatched based on the market price of wood waste. This results in fuel cost savings that each partnership shares with Consumers’ customers. | ||||||
CMS Energy’s investment in these partnerships is included in investments on its consolidated balance sheets in the amount of $57 million as of December 31, 2014 and $56 million as of December 31, 2013. The creditors of these partnerships do not have recourse to the general credit of CMS Energy or Consumers, except through a guarantee provided by CMS Energy of $3 million annually. CMS Energy has deferred collections on certain receivables owed by Genesee. CMS Energy’s maximum exposure to loss from these receivables is $8 million. Consumers has not provided any financial or other support during the periods presented that was not previously contractually required. | ||||||

Significant_Accounting_Policie1
Significant Accounting Policies (Policy) | 12 Months Ended | |||
Dec. 31, 2014 | ||||
Principles of Consolidation | Principles of Consolidation: CMS Energy and Consumers prepare their consolidated financial statements in conformity with GAAP. CMS Energy’s consolidated financial statements comprise CMS Energy, Consumers, CMS Enterprises, and all other entities in which CMS Energy has a controlling financial interest or is the primary beneficiary. Consumers’ consolidated financial statements comprise Consumers and all other entities in which it has a controlling financial interest or is the primary beneficiary. CMS Energy uses the equity method of accounting for investments in companies and partnerships that are not consolidated, where they have significant influence over operations and financial policies but are not the primary beneficiary. CMS Energy and Consumers eliminate intercompany transactions and balances. | |||
Use of Estimates | Use of Estimates: CMS Energy and Consumers are required to make estimates using assumptions that may affect reported amounts and disclosures. Actual results could differ from those estimates. | |||
Revenue Recognition Policy - General | Revenue Recognition Policy: CMS Energy and Consumers recognize revenue from deliveries of electricity and natural gas, and from the transportation, processing, and storage of natural gas, when services are provided. CMS Energy and Consumers record unbilled revenue for the estimated amount of energy delivered to customers but not yet billed. CMS Energy and Consumers record sales tax net and exclude it from revenue. CMS Energy recognizes revenue on sales of marketed electricity, natural gas, and other energy products at delivery. | |||
Revenue Recognition Policy - Alternative-Revenue Programs | Alternative-Revenue Program: In 2009, the MPSC approved an energy optimization incentive mechanism that provides a financial incentive if the energy savings of Consumers’ customers exceed annual targets established by the MPSC. The maximum incentive that Consumers may earn under this mechanism is 15 percent of the amount it spends on energy optimization programs, which is limited to two percent of Consumers’ retail revenue. Consumers accounts for this program as an alternative-revenue program that meets the criteria for recognizing revenue related to the incentive as soon as energy savings exceed the annual targets established by the MPSC. | |||
Revenue Recognition Policy - Self-Implemented Rates | Self-Implemented Rates: Unless prohibited by the MPSC upon a showing of good cause, Consumers is allowed to self-implement new energy rates six months after a new rate case filing if the MPSC has not issued an order in the case. The MPSC then has another six months to issue a final order. If the MPSC does not issue a final order within that period, the filed rates are considered approved. If the MPSC issues a final order within that period, the rates that Consumers self-implemented may be subject to refund, with interest. Consumers recognizes revenue associated with self-implemented rates. If Consumers considers it probable that it will be required to refund a portion of its self-implemented rates, then Consumers records a provision for revenue subject to refund. | |||
Revenue Recognition Policy - EnerBank | EnerBank: EnerBank provides four types of unsecured consumer installment loans: same-as-cash, zero interest, reduced interest, and traditional. Under EnerBank’s same-as-cash programs, authorized contractors pay EnerBank a fee to provide a borrower with the option to pay off the loan interest-free during the same-as-cash period. EnerBank recognizes the fee on a straight-line basis over the same-as-cash period, which typically ranges from three to 24 months. If a borrower does not exercise its option to pay off its loan interest-free during the same-as-cash period, EnerBank charges the borrower accrued interest at the loan’s contractual rate on the outstanding balance from the origination date. Under the zero interest and reduced interest programs, authorized contractors pay EnerBank a fee to provide a borrower with no interest or reduced rates of interest for the entire term of the loan. EnerBank recognizes the fee using the interest method over the term of the loan, which ranges from one to 12 years. | |||
EnerBank recognizes interest income using the interest method and amortizes loan origination fees, net of certain direct origination costs, over the loan term. EnerBank ceases recognizing interest income when a loan loss is confirmed or when a loan becomes 120 days past due, at which time the loan principal is charged against the allowance for loan losses. At that time, EnerBank recognizes any interest accrued but not received for such loan losses as a reversal of interest income. | ||||
The loan fees and interest income earned by EnerBank are reported as operating revenue on CMS Energy’s consolidated statements of income. | ||||
Accounts Receivable | Accounts Receivable: Accounts receivable comprise trade receivables and unbilled receivables. CMS Energy and Consumers record their accounts receivable at cost, which approximates fair value. CMS Energy and Consumers establish an allowance for uncollectible accounts based on historical losses, management’s assessment of existing economic conditions, customer trends, and other factors. CMS Energy and Consumers assess late payment fees on trade receivables based on contractual past-due terms established with customers. CMS Energy and Consumers charge off accounts deemed uncollectible to operating expense. | |||
Cash and Cash Equivalents | Cash and Cash Equivalents: Cash and cash equivalents include short-term, highly liquid investments with original maturities of three months or less. | |||
Contingencies | Contingencies: CMS Energy and Consumers record estimated liabilities for contingencies on their consolidated financial statements when it is probable that a liability has been incurred and when the amount of loss can be reasonably estimated. CMS Energy and Consumers expense legal fees as incurred; fees incurred but not yet billed are accrued based on estimates of work performed. This policy also applies to any fees incurred on behalf of employees and officers under indemnification agreements; such fees are billed directly to CMS Energy or Consumers. | |||
Debt Issuance Costs, Discounts, Premiums, and Refinancing Costs | Debt Issuance Costs, Discounts, Premiums, and Refinancing Costs: Upon the issuance of long-term debt, CMS Energy and Consumers defer issuance costs, discounts, and premiums and amortize those amounts over the terms of the associated debt. Upon the refinancing of long-term debt, Consumers, as a regulated entity, defers any remaining unamortized issuance costs, discounts, and premiums associated with the refinanced debt and amortizes those amounts over the term of the newly issued debt. For the non‑regulated portions of CMS Energy’s business, any remaining unamortized issuance costs, discounts, and premiums associated with extinguished debt are charged to earnings. | |||
Derivative Instruments | Derivative Instruments: In order to support ongoing operations, CMS Energy and Consumers enter into contracts for the future purchase and sale of various commodities, such as electricity, natural gas, and coal. These forward contracts are generally long-term in nature and result in physical delivery of the commodity at a contracted price. Most of these contracts are not subject to derivative accounting because: | |||
· | they do not have a notional amount (that is, a number of units specified in a derivative instrument, such as MWh of electricity or bcf of natural gas); | |||
· | they qualify for the normal purchases and sales exception; or | |||
· | there is not an active market for the commodity. | |||
Consumers’ coal purchase contracts are not derivatives because there is not an active market for the coal it purchases. If an active market for coal develops in the future, some of these contracts may qualify as derivatives. Since Consumers is subject to regulatory accounting, the resulting fair value gains and losses would be deferred as regulatory assets or liabilities and would not affect net income. | ||||
Consumers also uses FTRs to manage price risk related to electricity transmission congestion. An FTR is a financial instrument that entitles its holder to receive compensation or requires its holder to remit payment for congestion-related transmission charges. Consumers accounts for FTRs as derivatives. All changes in fair value associated with FTRs are deferred as regulatory assets and liabilities until the instruments are settled. | ||||
CMS Energy and Consumers record derivative contracts that do not qualify for the normal purchases and sales exception at fair value on their consolidated balance sheets. Each reporting period, the resulting asset or liability is adjusted to reflect any change in the fair value of the contract. Since none of CMS Energy’s or Consumers’ derivatives has been designated as an accounting hedge, all changes in fair value are either reported in earnings or deferred as regulatory assets or liabilities. CMS Energy and Consumers did not have significant amounts recorded as derivative assets or liabilities at December 31, 2014 or 2013. Additionally, the gains and losses recognized in earnings were not significant for the years ended December 31, 2014, 2013, or 2012. | ||||
Determination of Pension and OPEB MRV of Plan Assets | Determination of MRV of Plan Assets for DB Pension Plan and OPEB Plan: CMS Energy and Consumers determine the MRV for DB Pension Plan assets as the fair value of plan assets on the measurement date, adjusted by the gains or losses that will not be admitted into the MRV until future years. CMS Energy and Consumers reflect each year’s gain or loss in the MRV in equal amounts over a five-year period beginning on the date the original amount was determined. CMS Energy and Consumers determine the MRV for OPEB Plan assets as the fair value of assets on the measurement date. CMS Energy and Consumers use the MRV in the calculation of net DB Pension Plan and OPEB Plan costs. For further details, see Note 12, Retirement Benefits. | |||
Earnings Per Share | Earnings Per Share: CMS Energy calculates basic and diluted EPS using the weighted-average number of shares of common stock and dilutive potential common stock outstanding during the period. Potential common stock, for purposes of determining diluted EPS, includes the effects of non‑vested stock awards and contingently convertible securities. CMS Energy computes the effect on potential common stock using the treasury stock method or the if‑converted method, as applicable. Diluted EPS excludes the impact of antidilutive securities, which are those securities resulting in an increase in EPS or a decrease in loss per share. For EPS computations, see Note 15, Earnings Per Share – CMS Energy. | |||
Financial Instruments | Financial Instruments: CMS Energy and Consumers record debt and equity securities classified as available for sale at fair value as determined from quoted market prices or other observable, market-based inputs. Unrealized gains and losses resulting from changes in fair value of these securities are determined on a specific-identification basis. CMS Energy and Consumers report unrealized gains and losses on these securities, net of tax, in equity as part of AOCI, except that unrealized losses determined to be other than temporary are reported in earnings. For additional details regarding financial instruments, see Note 7, Financial Instruments. | |||
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets and Equity Method Investments: CMS Energy and Consumers perform tests of impairment if certain triggering events occur or if there has been a decline in value that may be other than temporary. | |||
CMS Energy and Consumers evaluate long-lived assets held in use for impairment by calculating the undiscounted future cash flows expected to result from the use of the asset and its eventual disposition. If the undiscounted future cash flows are less than the carrying amount, CMS Energy and Consumers recognize an impairment loss equal to the amount by which the carrying amount exceeds the fair value. CMS Energy and Consumers estimate the fair value of the asset using quoted market prices, market prices of similar assets, or discounted future cash flow analyses. | ||||
Impairment of Equity Method Investments | CMS Energy also assesses equity method investments for impairment whenever there has been a decline in value that is other than temporary. This assessment requires CMS Energy to determine the fair value of the equity method investment. CMS Energy determines fair value using valuation methodologies, including discounted cash flows, and assesses the ability of the investee to sustain an earnings capacity that justifies the carrying amount of the investment. CMS Energy records an impairment if the fair value is less than the carrying amount and the decline in value is considered to be other than temporary. | |||
Inventory - Gas and Coal | Inventory: CMS Energy and Consumers use the weighted-average cost method for valuing working gas, recoverable base gas in underground storage facilities, and materials and supplies inventory. CMS Energy and Consumers also use this method for valuing coal inventory, and they classify these amounts as generating plant fuel stock on their consolidated balance sheets. | |||
Inventory - RECs and Emission Allowances | CMS Energy and Consumers account for RECs and emission allowances as inventory and use the weighted-average cost method to remove amounts from inventory. RECs and emission allowances are used to satisfy compliance obligations related to the generation of power. | |||
Inventory - Impairment | CMS Energy and Consumers use the lower-of-cost-or-market method to evaluate inventory for impairment. | |||
Accounting for MISO Transactions | MISO Transactions: MISO requires the submission of hourly day-ahead and real-time bids and offers for energy at locations across the MISO region. CMS Energy and Consumers account for MISO transactions on a net hourly basis in each of the real-time and day-ahead markets, netted across all MISO energy market locations. CMS Energy and Consumers record net hourly purchases in purchased and interchange power and net hourly sales in operating revenue on their consolidated statements of income. They record net billing adjustments upon receipt of settlement statements, record accruals for future net purchases and sales adjustments based on historical experience, and reconcile accruals to actual expenses and sales upon receipt of settlement statements. | |||
Property Taxes | Property Taxes: Property taxes are based on the taxable value of Consumers’ real and personal property assessed by local taxing authorities. Consumers records property tax expense over the fiscal year of the taxing authority for which the taxes are levied based on Consumers’ budgeted customer sales. The deferred property tax balance represents the amount of Consumers’ accrued property tax that will be recognized over future governmental fiscal periods. | |||
Reclassifications | Reclassifications: CMS Energy and Consumers have reclassified certain prior-period amounts on their consolidated financial statements to conform to the presentation for the current period. These reclassifications did not affect consolidated net income or cash flows for the periods presented. | |||
Renewable Energy Grant | Renewable Energy Grant: In 2013, Consumers received a renewable energy cash grant for Lake Winds® Energy Park under Section 1603 of the American Recovery and Reinvestment Tax Act of 2009. Upon receipt of the grant, Consumers recorded a regulatory liability, which Consumers is amortizing over the life of Lake Winds® Energy Park. Consumers presents the amortization as a reduction to maintenance and other operating expense. Consumers recorded the deferred income taxes related to the grant as a reduction of the book basis of Lake Winds® Energy Park. | |||
Restricted Cash and Cash Equivalents | Restricted Cash and Cash Equivalents: CMS Energy and Consumers have restricted cash and cash equivalents dedicated for repayment of Securitization bonds and for payment under performance guarantees. CMS Energy and Consumers classify these amounts as a current asset if they relate to payments that could or will occur within one year. | |||
Consumers Energy Company [Member] | ||||
Principles of Consolidation | Principles of Consolidation: CMS Energy and Consumers prepare their consolidated financial statements in conformity with GAAP. CMS Energy’s consolidated financial statements comprise CMS Energy, Consumers, CMS Enterprises, and all other entities in which CMS Energy has a controlling financial interest or is the primary beneficiary. Consumers’ consolidated financial statements comprise Consumers and all other entities in which it has a controlling financial interest or is the primary beneficiary. CMS Energy uses the equity method of accounting for investments in companies and partnerships that are not consolidated, where they have significant influence over operations and financial policies but are not the primary beneficiary. CMS Energy and Consumers eliminate intercompany transactions and balances. | |||

Allowance For Loan Losses Policy | The allowance for loan losses is a valuation allowance to reflect estimated credit losses. The allowance is increased by the provision for loan losses and decreased by loan charge-offs net of recoveries. Management estimates the allowance balance required by taking into consideration historical loan loss experience, the nature and volume of the portfolio, economic conditions, and other factors. Loan losses are charged against the allowance when the loss is confirmed, but no later than the point at which a loan becomes 120 days past due. |

1 | In 2007, Consumers sold Palisades to Entergy and entered into a 15-year PPA to buy all of the capacity and energy then capable of being produced by Palisades. Consumers has continuing involvement with Palisades through security provided to Entergy for Consumers’ PPA obligation and other arrangements. Because of these ongoing arrangements, Consumers accounted for the transaction as a financing of Palisades and not a sale. Accordingly, no gain on the sale of Palisades was recognized on the consolidated statements of income. Consumers accounted for the remaining non-real-estate assets and liabilities associated with the transaction as a sale. | ||||||||||
Palisades remains on Consumers’ consolidated balance sheets and Consumers continues to depreciate it. Consumers recorded the related proceeds as a finance obligation with payments recorded to interest expense and the finance obligation based on the amortization of the obligation over the life of the Palisades PPA. The value of the finance obligation was determined based on an allocation of the transaction proceeds to the fair values of the net assets sold and fair value of the plant asset under the financing. Total amortization and interest charges under the financing were $19 million for the year ended December 31, 2014 and $20 million for each of the years ended December 31, 2013 and December 31, 2012. | |||||||||||

1 | The discount rate reflects the rate at which benefits could be effectively settled and is equal to the equivalent single rate resulting from a yield curve analysis. This analysis incorporated the projected benefit payments specific to CMS Energy’s and Consumers’ DB Pension Plan and OPEB Plan and the yields on high quality corporate bonds rated Aa or better. | |||||||||||||||||||||
2 | The mortality assumption for 2014 for benefit obligations was based on the new RP‑2014 mortality table, with projection scale MP‑2014. The mortality assumption for 2013 and 2012 was based on the RP‑2000 mortality tables with projection of future mortality improvements using Scale AA, which aligned with the IRS prescriptions for cash funding valuations under the Pension Protection Act of 2006. The mortality assumption for all three years for net periodic benefit cost was based on the RP‑2000 mortality table. | |||||||||||||||||||||
3 | CMS Energy and Consumers determined the long-term rate of return using historical market returns, the present and expected future economic environment, the capital market principles of risk and return, and the expert opinions of individuals and firms with financial market knowledge. CMS Energy and Consumers considered the asset allocation of the portfolio in forecasting the future expected total return of the portfolio. The goal was to determine a long-term rate of return that could be incorporated into the planning of future cash flow requirements in conjunction with the change in the liability. Annually, CMS Energy and Consumers review for reasonableness and appropriateness the forecasted returns for various classes of assets used to construct an expected return model. CMS Energy’s and Consumers’ expected long-term rate of return on DB Pension Plan assets was 7.5 percent in 2014. The actual return on DB Pension Plan assets was 7.4 percent in 2014, 12.5 percent in 2013, and 14.1 percent in 2012. | |||||||||||||||||||||

1 | The discount rate reflects the rate at which benefits could be effectively settled and is equal to the equivalent single rate resulting from a yield curve analysis. This analysis incorporated the projected benefit payments specific to CMS Energy’s and Consumers’ DB Pension Plan and OPEB Plan and the yields on high quality corporate bonds rated Aa or better. | |||||||||||||||||||||
2 | The mortality assumption for 2014 for benefit obligations was based on the new RP‑2014 mortality table, with projection scale MP‑2014. The mortality assumption for 2013 and 2012 was based on the RP‑2000 mortality tables with projection of future mortality improvements using Scale AA, which aligned with the IRS prescriptions for cash funding valuations under the Pension Protection Act of 2006. The mortality assumption for all three years for net periodic benefit cost was based on the RP‑2000 mortality table. | |||||||||||||||||||||
3 | CMS Energy and Consumers determined the long-term rate of return using historical market returns, the present and expected future economic environment, the capital market principles of risk and return, and the expert opinions of individuals and firms with financial market knowledge. CMS Energy and Consumers considered the asset allocation of the portfolio in forecasting the future expected total return of the portfolio. The goal was to determine a long-term rate of return that could be incorporated into the planning of future cash flow requirements in conjunction with the change in the liability. Annually, CMS Energy and Consumers review for reasonableness and appropriateness the forecasted returns for various classes of assets used to construct an expected return model. CMS Energy’s and Consumers’ expected long-term rate of return on DB Pension Plan assets was 7.5 percent in 2014. The actual return on DB Pension Plan assets was 7.4 percent in 2014, 12.5 percent in 2013, and 14.1 percent in 2012. | |||||||||||||||||||||

[1] | In 2007, Consumers sold Palisades to Entergy and entered into a 15-year PPA to buy all of the capacity and energy then capable of being produced by Palisades. Consumers has continuing involvement with Palisades through security provided to Entergy for Consumers’ PPA obligation and other arrangements. Because of these ongoing arrangements, Consumers accounted for the transaction as a financing of Palisades and not a sale. Accordingly, no gain on the sale of Palisades was recognized on the consolidated statements of income. Consumers accounted for the remaining non-real-estate assets and liabilities associated with the transaction as a sale.Palisades remains on Consumers’ consolidated balance sheets and Consumers continues to depreciate it. Consumers recorded the related proceeds as a finance obligation with payments recorded to interest expense and the finance obligation based on the amortization of the obligation over the life of the Palisades PPA. The value of the finance obligation was determined based on an allocation of the transaction proceeds to the fair values of the net assets sold and fair value of the plant asset under the financing. Total amortization and interest charges under the financing were $19 million for the year ended December 31, 2014 and $20 million for each of the years ended December 31, 2013 and December 31, 2012. |

[1] | The discount rate reflects the rate at which benefits could be effectively settled and is equal to the equivalent single rate resulting from a yield curve analysis. This analysis incorporated the projected benefit payments specific to CMS Energy’s and Consumers’ DB Pension Plan and OPEB Plan and the yields on high quality corporate bonds rated Aa or better. | |||||
[2] | The mortality assumption for 2014 for benefit obligations was based on the new RP2014 mortality table, with projection scale MP2014. The mortality assumption for 2013 and 2012 was based on the RP2000 mortality tables with projection of future mortality improvements using Scale AA, which aligned with the IRS prescriptions for cash funding valuations under the Pension Protection Act of 2006. The mortality assumption for all three years for net periodic benefit cost was based on the RP2000 mortality table. | |||||
[3] | CMS Energy and Consumers determined the long-term rate of return using historical market returns, the present and expected future economic environment, the capital market principles of risk and return, and the expert opinions of individuals and firms with financial market knowledge. CMS Energy and Consumers considered the asset allocation of the portfolio in forecasting the future expected total return of the portfolio. The goal was to determine a long-term rate of return that could be incorporated into the planning of future cash flow requirements in conjunction with the change in the liability. Annually, CMS Energy and Consumers review for reasonableness and appropriateness the forecasted returns for various classes of assets used to construct an expected return model. CMS Energy’s and Consumers’ expected long-term rate of return on DB Pension Plan assets was 7.5 percent in 2014. The actual return on DB Pension Plan assets was 7.4 percent in 2014, 12.5 percent in 2013, and 14.1 percent in 2012. |
